Question

. A ray of light is traveling from air to water. What is the angle of incidence in air, if the angle of refraction in water is 41o? Take refractive index of water = 1.32 and sin41o = 0.6561. (A: 60o)

Answer 1

Answer:  60 degree

Explanation: by using snells law

sin i x n1=sin r x n2

sin I=sin 40

n1= refractive index of water

n2=refractive index of water
