Hi, I have the following question:

1. The index of refraction for a prism is given by the equation:

n = 1.58 − (6.41 x 10^4)λ

where λ is the wavelength in meters. Light is incident at 28°.
Find the exit angle ß for light of
a) 800 nm
b) 633 nm
c) 540 nm

2. Will lower wavelengths be allowed to exit the prism? Why or why not?
