The figure shows a point source of unpolarized light at A inside a uniform transparent crystal. The ray AO in the crystal strikes the plane surface SS' making an angle of 30° with the normal. This angle is the critical angle for transmission into air.

-Determine the index of refraction of the crystal.
A)0.58
B)1.2
C)1.7
D)2.0
E)2.4
