When unpolarized light is incident at the Brewster angle on a dielectric surface:

Answer:

A, C, D

Solution:

At Brewster angle $θ_{B}$ : $tan θ_{B} = \frac{n _{2}}{n _{1}}$

$r_{∥} = 0$ at $θ = θ_{B}$ ⟹ (A) is true, and (B) is false.

$θ_{r} = θ_{i}$

At Brewster condition: $θ_{i} = θ_{B} \Rightarrow θ_{r} = θ_{B}$ ⟹ (C) is true.

The transmitted wave contains both components ( $∥$ and $⊥$ ) ⟹(D) is true.
