Optical Path

This program is designed to demonstrate the laws of reflection and refraction of light. When the laser pointer is moved, the green laser beam shoots from the air into the water. The angle of reflection in the optical path is equal to the angle of incidence, and the ratio of the sine of the angle of incidence to the sine of the angle of refraction is equal to the ratio of the refractive index of pure water to that of air (approximately 1.333). This app is suitable for primary and middle school students to understand the laws of reflection and refraction of light through interactive operations, enabling them to learn and consolidate physics knowledge during leisure and entertainment. It can also be used by teachers for classroom lectures.
