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.

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

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