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
