## Homework Statement

A parallel beam of light containing two wavelengths, λ

_{1}= 400 nm and λ

_{2}= 650 nm, enters the silicate flint glass (at a angle of 41 degrees, relative to normal) of an equilateral triangle (60 degrees at each angle) prism. At what angle, relative to the normal, does each beam leave the prism.

## Homework Equations

n

_{air}⋅ sinθ

_{1}= n

_{prism}⋅ sinθ

_{2}

## The Attempt at a Solution

I don't get how to get the two different indices of refraction for the prism, one for each given wavelength.
