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.
-If point A is 16 cm below the plane SS',what is the radius of the largest circle at the air-crystal interface through which light can emerge from the crystal?
