Question

When an unpolarized plane electromagnetic wave in a dielectric medium with refractive index $n_1$ is incident on a plane interface separating it from another dielectric medium with refractive index $n_2$ (where $n_2 > n_1$), and the angle of incidence is $\tan^{-1} \left( \frac{n_2}{n_1} \right)$, the following statement is true:

• A. The reflected wave is unpolarized
• B. The reflected wave is polarized parallel to the plane of incidence
• C. The reflected wave is polarized perpendicular to the plane of incidence
• D. There is no transmitted wave

Answer 1

Answer: (C)

The reflected wave is polarized perpendicular to the plane of incidence

Answer 2

The correct option is (C) :The reflected wave is polarized perpendicular to the plane of incidence
