Answer:
1. The incident ray, refracted ray, and the normal lie on the same plane.
2. According to Snell’s law of refraction, the ratio of the sine of the angle of incidence to the sine of the angle of refraction is a constant.
Explanation:
The two laws followed by a beam of light as it transfers through two media are as follows:
1. The incident ray, refracted ray, and the normal lie on the same plane.
2. According to Snell’s law of refraction, the ratio of the sine of the angle of incidence to the sine of the angle of refraction is a constant.
