Make an animation of light reflection and refraction
The following are the general steps for creating a light reflection and refraction animation: ** 1. Selection of animation software ** You can choose a powerful online animation production platform, such as Xiuzhan. It can make the creation of popular science animation simple and efficient. ** 2. Principle Understanding and Scene Construction ** 1. ** Principle Basics ** - The reflection of light was the phenomenon of light waves bouncing back from the interface, while refraction was the phenomenon of light waves changing their direction of transmission when they passed through the interface and entered another medium. According to the law of reflection, when a ray of light enters another medium from one medium, the angle of incidence is equal to the angle of reflection. According to Snell's law, when a ray of light enters another medium from one medium, there is a certain relationship between the angle of incidence, the angle of refraction, and the index of refraction of the two media. - For example, when sunlight passes through raindrops, light is refracted, reflected, and refracted again, forming an optical phenomenon called a rainbow. Different media had different refraction index. For example, the refraction index of air was close to 1, and the refraction index of glass was around 1.5. This difference caused light to be reflected and refracted at the interface of different media. 2. ** Scene Setting ** - Take the glass sphere as an example. Glass spheres had refraction and reflection properties. To calculate the direction of reflection and refraction, you need to know the direction of the intersection of the ray and the ball, the normal at the intersection, and the direction of the incident ray (the main ray). In order to calculate the direction of refraction, you also need to specify the index of refraction of the material (such as glass). - Suppose a scene was constructed where light shot from the air into the glass ball and then shot out from the glass ball into the air. ** 3. The animation production process ** 1. ** Light Drawing ** - Draw a ray of light (which can be represented by a line) from the air to the surface of the glass ball. This ray of light would be the main ray of light, and its direction would be determined. For example, it would be incident at a certain angle. 2. ** Reflection part ** - According to the law of reflection, the direction of the reflected light was calculated. When the ray of light reaches the surface of the glass ball, the reflection ray is drawn at the point of incidence so that the angle of incidence is equal to the angle of reflection. The reflection direction can be determined by calculating the normal at the intersection and the direction of the main ray. The color of the reflected light can be the same as that of the incident light or can be set according to needs. 3. ** Refraction part ** - Considering the glass ball's index of refraction (assumed to be around 1.5), the direction of the refracted light was calculated according to Snell's law. When light entered the glass ball, the medium changed from air to glass, so the light would be refracted and change direction. In the animation, the path of light in the glass ball was shown. When the light shot out of the glass ball into the air, the direction of the refracted light was calculated according to Snell's law again. Because the medium changed from glass to air, the light refracted again. 4. ** Animation Effects ** - Set the speed of light transmission (you can adjust the frame rate according to actual needs) to make the entire reflection and refraction process look more natural. For example, an animation of 15 - 30 frames per second could better show the transmission of light. - Some auxiliary elements could be added, such as a label that showed the angle, to show the relationship between the angle of incidence, the angle of reflection, and the angle of refraction. At the same time, in order to make the animation more vivid, the color of the light could be gradually changed, such as gradually changing from white to light blue. Read more exciting novels for free
What's the standard antonemy of hot?
The standard antonemy of "hot" was "cold". From a semantical point of view," hot " meant that the temperature was high and felt high, while " cold " meant that the temperature was low and felt low. The two were in the opposite state in terms of temperature. In addition, in the relative relationship of words,"hot" and "cold" were a pair of common antonyms, such as "hot water" and "cold water","tropical" and "frigid zone" and other word structures also reflected this antonymy relationship. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Kung Fu Liu Yifei's stills
In the King of Kung Fu, Liu Yifei had a stills photo of her playing the role of the Golden Swallow. In 2007, after Jet Li and Chan Chan announced their collaboration, many actresses competed for the female lead role. Liu Yifei won the role of the Golden Swallow because the director's family liked her role as Wang Yuyan. In addition, during the filming of the movie Hua Mulan, Liu Yifei's martial arts stunt double was exposed. The stunt double was wearing the same Hua Mulan costume as Liu Yifei and had the same wavy hairstyle. It could also be used as a reference for stills related to "Kung Fu"(because the Hua Mulan character had martial arts related content).
