Question

4. The ratio of sine of angle of incidence to the sine of angle of refraction is a constant, for the light of given colour and for the given pair of media. What is the name of this law?​

Answer 1

Answer:

Snell's law of refraction

The ratio of sine of angle of incidence to the sine of angle of refraction is a constant, for the light of a given color and for the given pair of media. This law is also known as Snell's law of refraction. This constant is also called the refractive index of the second medium with respect to the first.
