In Figure, light is incident at angle 0,=40.1° on a boundary between two
transparent materials. Some of the light travels down through the next
three layers of transparent materials, while some of it reflects upward and
then escape into the air. If n;=1.3, n,= 1.4, n;=1.32, and ng= 1.45, what is

A light beam strikes a piece of glass with an incident angle of 45.00°. The beam contains two colors: 450.0 nm and an unknown
wavelength. The index of refraction for the 450.0-nm light is 1.482. Assume the glass is surrounded by air, which has an index of
refraction of 1.000.
Determine the index of refraction n, for the unknown
wavelength if its refraction angle is 0.6950° greater than that
of the 450.0 nm light.
