Question

State Snell's law of refraction of light.
​

Answer 1

Answer:

sin i = sin r

Explanation:

The sine of angle of incidence is equal to the sine of the angle of refraction.

sin i / sin r = n

Answer 2

Answer:

The ratio of sine of angle of incidence to the sine of angle of refraction is constant for a given pair of media

sine of angle of incidence/ sine of angle of refraction= constant

OR

sin i / sin r = constant
