Quizplus · Accepted Answer

The angle of incidence for maximum polarization by reflection from a non-magnetic medium is given by Brewster's Law which states that tanθ_p = n, where θ_p is the polarization angle and n is the refractive index of the medium. Rearranging the equation, we get θ_p = tan^(-1)(n) = tan^(-1)(1.33) ≈ 53º. Therefore, the answer is B.

The Index of Refraction of Water Is Approximately 1
