Homework Help: Physics

Posted by Joseph on Sunday, March 7, 2010 at 11:26pm.

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 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?
