The figure below shows the path of a beam of light through several layers with different indices of refraction. (Assume n4 = 1.10.)
(a) If θ1 = 32.0°, what is the angle θ2 of the emerging beam?
(b) What is the smallest incident angle θ1 to have total internal reflection at the surface between the medium with n = 1.20 and the medium with n4 = 1.10?
Homework Answers
a)
given
n4 = 1.10
if θ1 = 32 degrees
from the relation
n1sin θ1 = n2sin θ2
θ2 = sin^-1(1.6*sin32/1.1) = 50.425 degrees
b)
θ1 = sin^-1(1.10*sin90/1.60) = 43.4 degrees
