(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A sheet of glass has n_red=1.52 and n_violet=1.55. A narrow beam of white light is incident on the glass at 27.0 degrees

What is the angular spread of the light inside the glass?

2. Relevant equations

Snells Law: theta2 = arc sin (n1 sin theta1)/n2

3. The attempt at a solution

I tried two ways of answering this question and neither has worked. First I made two equations: n1=red(1.51), theta1=27, n2=air(1.00)...then a second equation with n1=violet(1.55)...then subtracted the two thetas

My second attmept was to set n1=glass(1.5)...all else the same as above

Neither attempt was correct, can someone please help??
