(a) what is the angle of incidence?
 (b) the light refracted into the water is intecepted by the top flat surface of a block of glass with index of n=1.50. The light reflected from the glass is completely linearly polarized. What is the angle between the glass and the water surface?
 (Please show solutions for both a and b)
Solution
thetai = thetap = tan-1(1.33)
= 53.06 deg
thetat = 90 - 53.06 = 36.94 deg
------------------------------------------------
From water to glass
thetai = thetap = tan-1(nt / ni)
thetai\' = thetap = tan-1(1.50 / 1.33) = 48.44 deg
The angle between glass and water surface
angle = thetai\' - thetat
= 48.44 - 36.94 = 11.5 deg
