Thanks a lot lowlypion. I had a little trouble figuring out why your values didn't work, but in the end I found that the values were actually: d/(d2 + h2)1/2 for the top angle and (d/2)/(d2/4 + h2)1/2 for the liquid angle. All in all though, you greatly helped me. Thank you so much!

You mean \frac{n_1}{n_2} = \frac {Sin \theta_2}{Sin \theta_1} So let's say n1 = n2 when the glass is empty because the angle of incident is equal to the angle of refraction. When the glass is full, n2 = 1.22 and everything else is unknown. So how would I go about finding just theta r...
