Ok so here's a homework question. I honestly dont know where to begin.(adsbygoogle = window.adsbygoogle || []).push({});

A prism with an apex angle of 40 degrees induces a minimum deviation of 20 degrees. What is the prism made of.

Judging by what the question is asking for, I think I need to find the refractive index thru Snells law, but i dont know where to start.

All help is appreciated.
