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

question 20

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.
$The figure shows a point source of unpolarized light at A inside a uniform transparent crystal. The ray AO in the crystal strikes the plane surface SS' making an angle of 30° with the normal. This angle is the critical angle for transmission into air. -Which one of the following statements is true concerning this situation? A) When the angle of incidence is equal to the Brewster angle,the angle of refraction is 13°. B) When the angle of incidence is equal to the Brewster angle,the angle of refraction is 63°. C) When the angle of incidence is equal to the Brewster angle,the angle of refraction is 42°. D) Since the Brewster angle is less than the critical angle,there is no refraction when the angle of incidence is equal to qB. E) Since the Brewster angle is greater than the critical angle,there is no refraction when the angle of incidence is equal to q B.$
-Which one of the following statements is true concerning this situation?
