Answer:
angle of refraction at first surface is 22.74°
Step-by-step explanation:
Given data
thickness = 1.50 cm
n = 1.52
angle = 36.0°
to find out
angle of refraction at first surface
solution
we will apply here Snells law that is
n1 sinθ1 = n2 sinθ2
θ2 = sin^-1 ( n1/n2) sin θ1
here n1 is 1 and n2 is 1.52 and θ1 = 36.0°
θ2 = sin^-1 ( n1/n2) sin θ1
θ2 = sin^-1 ( 1 / 1.52 ) sin36
θ2 = 22.74°
angle of refraction at first surface is 22.74°
