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.

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 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 minerals?
I don't quite understand your expression. You want to ask about the principle of light reflection in minerals, and you also want the relevant pictures? If that was the case, the reflection of light and shadow was mainly due to the crystal structure and chemical composition of the minerals. Different crystal structures and chemical compositions would affect the transmission and reflection of light, resulting in different light and shadow effects.

The Light Reaction Principle of Purple Light
The reaction principle of the purple light was as follows: The fluorescent reaction of a purple light lamp was based on the principle of luminescence. When a violet light (a violet flashlight) shone on certain substances, these substances would selectively absorb the violet light emitted by the violet light. The molecules would be stimulated, and they would emit visible light of the same wavelength and different intensity. When the light stopped, the fluorescence disappeared. When the infrared rays hit the fluorescent substance, there were three general situations: part of the infrared rays were reflected; part of the infrared rays were absorbed by the fluorescent substance; and part of the infrared rays were transmitted. The fluorescence occurred due to the absorption of the fluorescent substance. After the fluorescent substance absorbed the infrared rays, the internal energy state of the molecules changed, showing a transition between different energy levels and releasing fluorescence. For the Lighthouse series of purple lamps, the principle of light was to bombard the special fluorescent material inside the lamp with electric arcs after being energized, and then produce purple spectrum light waves. The violet light could be divided into the UUA band (320 - 400 <anno data-annotation-id ="00000100 - 400a-400a-400a-800a-8000000000000"> wave-length </anno>), the UVP band (275 - 320 </anno>), the UVP band (200 - 275 </anno>), and the UVR band (100 - 200 </anno>). Among them, the fluorescent powder in the purple tube could convert the arc energy into long-wave violet radiation in the UVA-band, such as the UVA-band of 340 - 380 run, and the UVA-band of 365 run was more suitable for checking the fine traces of the collection and fluorescent anti-counterfeit work. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Light Sail Spaceship Principle
The principle of the light sail spacecraft was to use the light pressure produced by the photon to obtain thrust. In the universe, the photons emitted by the stars were like the wind generated by the atmospheric circulation on Earth. They could become the power source for the spacecraft to move forward. When the light sail expanded to a large enough area, the thrust generated by the photon impact on the light sail would cause the spacecraft to move. For example, the light sail of the light sail spacecraft was made of special materials, such as aluminum plated Myra. Its thickness could be as thin as a few hundred atoms in diameter. When the spaceship was illuminated by light, it could use the light sail to carry the light pressure to obtain energy and continue to accelerate. For example, the spacecraft in the " Breakthrough Starshot " program of the United States only weighed about 10 grams. It was integrated with a variety of small but efficient instruments. The external light sail could theoretically accelerate the spacecraft to tens of thousands of kilometers per second in a few minutes under the illumination of light, and finally stabilize at 20% of the speed of light.
