Im doing physics 20 in correspondance this summer, and Im stuck on a question about Refraction... and Snell's law.

The question is...

A ray of light is incident upon a 60-60-60 degree prism, n=1.5. Then it shows a diagram , and it asks to find the angle of reflection.. and other angles within the prism.

my question is, is that are there any resources around in the internet where I can find practise questions to help me with this question. thanks

actually i got the answer never mind.

sin r=sini/n=sin45/1.5=>r=sin-1[sin45/1.5]=28.13degree
