reflection and refraction
USD 0.99 · Designed for iPad
This program demonstrates the laws of refraction and reflection of light of different colors in various media, including the phenomenon of total internal reflection.
This program is designed to illustrate the laws of reflection and refraction of light. As the laser pointer moves, the laser beam enters from one medium to another. When the two media differ, both reflection and refraction occur. When the refractive index of the upper medium is greater than that of the lower medium, a fascinating phenomenon of total internal reflection can be observed when the angle of incidence exceeds the critical angle. This program is suitable for primary and secondary school students to learn and understand the laws of reflection and refraction of light, allowing them to review and consolidate their physics knowledge through interactive and enjoyable operations. It can also be used by teachers for classroom demonstrations, making lessons more lively and engaging.
The main functions of this program include:
1. Demonstrating the laws of reflection and refraction when the upper and lower media differ: The angle of reflection equals the angle of incidence, and the ratio of the sines of the angles of incidence and refraction equals the ratio of the refractive indices of the lower and upper media.
2. Demonstrating the phenomenon of total internal reflection when the refractive index of the upper medium is greater than that of the lower medium: When the angle of incidence exceeds the critical angle, all incident light is reflected back, with no refracted light.
3. Offering a choice of five laser colors - red, blue, green, orange, and purple - each corresponding to a different refractive index. Lasers with higher frequencies correspond to higher refractive indices.

1. Increased the variety of upper and lower media options, allowing the selection of multiple media types.
2. Added multiple laser colors, where for the same medium, different colors of laser light correspond to different refractive indices.
3. Enhanced with the demonstration of the phenomenon of total internal reflection.
4. Added localized support for multiple languages.
