Light passes from a material with index of refraction 1.25 to one with index of refraction 1.72. The angle of incidence is 34.3°. What is the angle of refraction?

angle of refraction is 24.17°

Explanation:

given data

index of refraction n1 = 1.25

index of refraction n2 = 1.72

angle of incidence θ1 = 34.3°

to find out

angle of refraction (θ2)

solution

we will apply here snells law that is

n1 sinθ1 = n2 sinθ2 ... 1

here put all these value and find θ2

1.25 sin34.3 = 1.72 sinθ2

sinθ2 = 0.70440 / 1.72

sinθ2 = 0.4095

θ2 = 24.17°

so here angle of refraction is 24.17°
