Question

Angle of incidence of a light ray in air medium is 45 degree angle of refraction is media of 30 degree find the refractive index

Answer 1

Answer:

sin i / sin r = refractive index of media

sin 45/sin30 = refractive index of media

refractive index of media = 1/√2 ÷ 1/2

refractive index of media = 1/√2 x 2 = 2/√2 = √2

thus the refractive index of media = √2

Answer 2

Answer:

refractive index of medium=√2
