A light of ray is incident at an angle of 58degrees on the plane surface of a block of glass of refractive index 1.60. Some light is reflected on the other side of the normal at the same angle as the angle of incidence.

Question

Find:

a.the angle between the light reflected from the surface and the light refracted into the glass
b.the deviation of the refracted ray

Answer 1

(a) sin r = sini/n =sin 58°/1.6=0.53
r =32 °
α=180°-58°-32°=90°
(b) δ= 58 -32 =26°

Answer 2

Thank you!
