Question

answer the following
state snall's law
​

Answer 1

Answer: The ratio of sine of angle of incidence to the sine of angle of refraction for light of given colour is constant for a given pair of media. This is known as Snell's law

Explanation:

sin i ÷ sin r = constant

Answer 2

Answer:

Snell's law states that in a plane the ratio of sine of angle of incidence is equal to sine of angle of angle is equal to a constant. this constant is the refractive index of the medium of the medium where the light is entering.

Mathematically:-

Sin i/Sin r= μ2/μ1=constant
