A ray of light is incident at an angle of 36.4 on the surface of a piece of crown glass hose index of refraction is 1.52 what is the angle of refraction in units of °

Answer 1

To answer this you use Snell's Law

n_isinθ_i=n_rsinθ_r

Since we are coming from air (n=1) into glass (n=1.52), it can be rewritten

(1)sin(36.4)=(1.52)sin(θr)

θ_r=sin^-1(sin36.4/1.52)
