Question

A ray of light travelling in air incident on the surface of a transparent medium at an angle of 45 degree with the surface . if bends by 15 degree form its path after reflection. find the refractive index of the medium.​

Answer 1

Answer:

answer is √2

Explanation:

n (refractve index ) = sin i / sin r

sin i = sin 45

sin r = sin30

n = 1 / √2 ÷1/2

n = 2 ÷ √2

n = √2
