1. The problem statement, all variables and given/known data
The figure shows a light ray incident on a glass cylinder where h = R/9. At what angle α will the ray be refracted?
(Image Attached)
2. Relevant equations
n(sin(theta))= N(sin(THETA))
3. The attempt at a solution
I'm not sure how to attack this problem. I've thought of using Snell's law:
1 sin (90) = 1.52 sin (THETA)
But I stopped myself midequation because then the R/9 is useless. I have decided to make R= 1 and then h= 1/9 (just to make things simple. I drew the picture and then extended out the refracted arrow, trying to figure out a way to use geometry, but I just can't place it.
Can anyone help me out?
Thanks in advance!
