(adsbygoogle = window.adsbygoogle || []).push({}); [SOLVED] Corner Reflector

1. The problem statement, all variables and given/known data

A corner reflector is to be made from a triangular prism with index of refraction n = 1.86, as shown in the diagram below. What is the maximum angle, with respect to the normal to the front surface of the prism, θ, such that total reflection will occur?

2. Relevant equations

[tex]n_{air}sin\theta_1 = n_{prism}sin\theta_2[/tex]

3. The attempt at a solution

I tried doing

[tex] 1 * sin\theta_1 = 1.86 * sin\ 90[/tex]

solving for [tex] \theta_1 [/tex] gives arcsin (1.86) which is undefined.

Any help appreciated
