-First, I used Snell's law to get the angle of refraction to be 30.1 degrees. However, I'm confused on how to construct my triangle? I made the long leg (y)= 19.7 m and I know it is a right triangle. Since I now have both the angles of refraction and incidence, where would they go in my triangle?

**drwls**, Saturday, February 19, 2011 at 4:22pmLet vat radius = r

To leave at the opposite edge, the beam must strike the middle of the vat bottom.

tan 30.1 = r/h = 0.5796

r = 11.42 m
