(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Light is incident along the normal to face AB of a glass prism of refractive index 1.66, as shown in the figure.

[PLAIN]http://img175.imageshack.us/img175/6339/yffigure3336.jpg [Broken]

Find [tex]\alpha[/tex]max, the largest value of the angle [tex]\alpha[/tex] such that no light is refracted out of the prism at face AC if the prism is immersed in air.

2. Relevant equations

I know I'm supposed to use Snells Law, but I really have no idea how to obtain the answer.

3. The attempt at a solution

I know that the incident angle is equal to 90 - [tex]\alpha[/tex] but thats all I know really.

Thanks
