The Figure Shows a Point Source of Unpolarized Light at a Inside

question 6

Multiple Choice

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?

• A)9.2 cm
• B)16.0 cm
• C)18.4 cm
• D)27.0 cm
• E)32.0 cm
