The Principle of Rainbow Light and Shadow in the kindergarten
The formation of rainbow light and shadow was related to refraction and reflection. Sunlight was actually a combination of seven colors of white light. When it was affected by certain optical conditions, color separation would occur. During the formation of the rainbow, there are many small water droplets that we can't see scattered in the air after the rain. These small water droplets can refracted and reflect sunlight. When sunlight enters the water droplet, it will be refracted into the water droplet. After the light is reflected once by the inner wall of the water droplet, it will be refracted out of the water droplet. This process includes two refracted and one reflected. Because different colors of light have different angles of refraction, the emitted light will form different colors. Finally, we can see a rainbow. Among them, the red light refracted at an angle of about 42°, and the purple light refracted at an angle of about 40°. Therefore, the light in the rainbow would be red in front and purple behind. This was the bright rainbow band that we usually saw, also known as the main rainbow. At the same time, there was a blurry rainbow outside the main rainbow, which was in the opposite color order from the main rainbow. It was called the secondary rainbow (neon). The secondary rainbow was formed by sunlight entering from the bottom of the water droplet, and after two reflections and two refraction. Due to the additional reflection, the rainbow's seven-color arrangement was opposite to the rainbow. Moreover, due to the additional reflection, a portion of the light was lost, so the brightness of the rainbow was lower than that of the rainbow. In kindergarten, there were some simple ways to demonstrate the principle of rainbow light and shadow. For example, using a triangular prism to refracted sunlight could break down white light into seven colors of light. This was because the triangular prism refracted different colors of light to different degrees. Purple light had the greatest degree of refraction, and red light had the smallest degree. Thus, one could see the colorful arrangement of light. Read more exciting novels for free
What is the principle of reflecting light and shadow?
The principle of light reflection could be explained by Huygens 'principle. Huygens' principle pointed out that every point on the spherical wave surface was a sub-wave source of a secondary spherical wave. The speed and frequency of the sub-wave were equal to the speed and frequency of the primary wave. The envelope of the sub-wave surface at each moment was the total wave surface at that moment. When light travels to different substances, it changes its direction of transmission at the interface and returns to the original substance. This is the reflection phenomenon of light. The reflected light and the incident light are on the same plane as the normal line. The reflected light and the incident light are separated on both sides of the normal line. The reflection angle is equal to the incident angle. In pictures, for example, the " ghostly shadow " phenomenon was the reflection of light through the lens of the camera, which was then captured by the LCD sensor. In the original art light and shadow production, reflection was a phenomenon caused by the reflection and refraction of light on the surface of the object. It could make the object in the picture interact with the environment to create a real light and shadow effect. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What is the principle of reflecting light and shadow?
When light travels to the interface between two media, if the degree of unsmoothness of the interface at the point of incidence is much smaller than the wave length, it can be regarded as a smooth interface. At this time, a part of the light will return to the original medium. This phenomenon is the reflection of light, which is also the principle of the reflection of light and shadow. The reflection of light on a smooth interface is called mirror reflection (or single-directional reflection). The reflected light, the incident light, and the normal are in the same plane. The reflected light and the incident light are on both sides of the normal, and the reflection angle is equal to the incident angle. If the interface is not smooth enough to be larger than the wave length, it will produce diffuse reflection. If there is both mirror reflection and diffuse reflection, it is called mixed reflection. If the brightness of light in different directions is the same in diffuse reflection, it is called uniform diffuse reflection. In the same reflection process, some of the light of some frequencies are reflected more, which is called selective reflection. It can use coating technology to change the optical properties of the interface of the medium, so that the reflected light can reduce or increase the light component of a certain frequency to adapt to the requirements of different optical components. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What is the principle of the light and shadow reflected by minerals?
When light shines on the mineral surface, it can produce optical phenomena such as transmission, absorption, refraction, and reflection. Minerals were composed of simple substances or compounds. There were various binding methods and binding forces between the different particles that made up the minerals. They could usually be divided into coax bonds, ion bonds, metal bonds, molecular bonds, hydrogen bonds, and so on. The outer layer of electrons of transparent minerals (dielectrics) composed of ion bonds, molecular bonds, or hydrogen bonds were bound electrons, which were fixed in a certain crystal lattice position around the ions. When the light wave radiates onto the bound electrons, it creates a forced vibration. Because the ground state and excited state of the electrons have a certain energy level, and the energy difference between most energy levels is larger than the energy of various visible light "photons", most of the visible light enters the mineral transmission, and only a small part of the visible light with the same energy difference is absorbed and the reflected light is very weak. As for the opaque minerals with metal bonds, their free electrons could move freely at the crystal lattice nodes. The energy interval between the electrons was much smaller than the energy of visible light's "photon". At the same time, there were more excited states, and the energy difference was equivalent to the energy of visible light's "photon". Therefore, when visible light hit the metal bond or part of the metal bond mineral surface, it could stimulate the ground state electrons to a certain excited state. The energy of the visible light itself was absorbed, and a part of it was converted into heat energy and consumed. Most of the energy was emitted as strong reflected light when the excited electrons returned to the ground state. In addition, when a beam of white light is reflected or transmitted into a faceting gem, because different colors of white light have different frequencies, they will have different refraction index, so the white light is broken down and presents a series of color spectrums. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

What is the principle of the light and shadow reflected by water?
The water reflection light shadow was mainly based on the following principles: 1. ** Reflection Principle **: - When light rays hit the surface of the water, the surface of the water acted as a medium boundary and would follow the law of reflection. In other words, the angle of incidence was equal to the angle of reflection. The incident angle is the angle between the light ray and the normal line of the water surface (the line that is vertical to the water surface), and the reflection angle is the angle between the reflected light ray and the normal line. - The surface of the water was relatively smooth, which allowed light to reflect regularly on its surface. If the water surface fluctuated, the direction of the reflected light would change with the fluctuation of the water surface, but it still followed the local law of reflection. 2. ** Refraction Principle **: - Water had a higher refraction index than air, and water was a light-dense substance compared to air. When a ray of light slanted from the air into the water, the direction of the ray of light would change. This was the phenomenon of refraction. The angle between the refracted ray and the normal (the angle of refraction) is smaller than the angle of incidence. - Different colors of light have slightly different degrees of refraction in water. For example, in the formation of a rainbow, when white light enters a water droplet (a medium similar to water), it is broken down into seven colors due to the different degrees of refraction of different colors of light. 3. ** Total Reflection Principle **: - When light travels from a dense medium (such as water) to a sparse medium (such as air), if the angle of incidence is greater than a certain critical angle, total reflection will occur. Total reflection allows light to be completely reflected back at the interface when it travels through the water. This is involved in some special optical phenomena or the use of optical fibers to transmit light.

What is the principle of light and shadow reflected by minerals? Video
When light shines on the mineral surface, it can produce optical phenomena such as transmission, absorption, refraction, and reflection. Minerals were composed of simple substances or compounds. There were various binding methods and binding forces between the different particles that made up the minerals. They could usually be divided into coax bonds, ion bonds, metal bonds, molecular bonds, hydrogen bonds, and so on. For transparent minerals (dieletes) composed of ion bonds, molecular bonds, or hydrogen bonds, the outer electrons were bound electrons, which were fixed in a certain crystal lattice position around the ions. When the light wave radiates on the bound electrons, it will cause forced vibration. Because the ground state and excited state of the electrons have a certain energy level, and the energy difference between most energy levels is larger than the energy of various visible light "photons", most of the visible light enters the mineral transmission. Only a small part of the visible light with the same energy difference is absorbed and the reflected light is very weak, so the reflection rate of these minerals is very low (<12%>). As for the opaque minerals with metal bonds, their free electrons could move freely at the lattice nodes. The energy interval of the electrons was much smaller than the energy of the visible light "photon". At the same time, there were more excited states, and the energy difference was equivalent to the energy of the visible light "photon". Therefore, when the visible light hit the metal bond or part of the metal bond mineral surface, the ground state electrons could be excited to a certain excited state. The energy of the visible light itself was absorbed, and a portion of it was converted into heat energy and consumed. Most of the energy was emitted as a strong reflection light when the excited state electrons returned to the ground state. Most of the "photons" were reflected, so the reflection rate of these minerals was higher (> 40%). In addition, when a beam of white light is reflected or transmitted into a faceting gem, because different colors of white light have different frequencies, they will have different refraction index, so the white light is broken down and presents a series of color spectrums. For example, the natural fiber of a mineral like sodium-borium ore could act as an optical fiber, transmitting light along its long axis through internal reflection. When a piece of sodium-borium ore was cut into a flat polished surface that was vertical to the fiber direction, a high-quality sample would show any surface image adjacent to the other side. In another case, the principle of spectral signatures suggests that each mineral absorbs and reflects light in a unique pattern, just like fingerprints. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

What is the principle behind the reflection of light and shadow on the water surface?
The reflection of light and shadow on the water surface was mainly due to the principle of light reflection. When light was emitted from a medium (such as air) to the surface of the water, a portion of the light would change its direction of transmission and return to the original medium (air), which formed a reflection. The surface of the water was relatively smooth, just like a mirror. It could reflect the light that shone on it according to a certain pattern, so that we could see the reflection of the water surface. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What is the principle of the phenomenon of the reflection of light and shadow on the water surface?
The reflection of light on the surface of the water was a reflection of light. The calm surface of the water was like a flat mirror. When light traveled to the surface of the water, it changed its direction of transmission on the water surface and returned to the original material (air), forming a reflection. In the reflection phenomenon, there are the following rules: the reflected light, the incident light, and the normal are all in the same plane; the reflected light and the incident light are on two sides of the normal; the reflection angle is equal to the incident angle. We can see objects because light is reflected from the object into our eyes. Similarly, when light enters the water from the air, due to the different refraction index of air and water, a part of the light will be reflected back, forming the reflection of the water surface that we see, such as the reflection in the water. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
