Question

Which of the following holds true for Brewster angle?

(a) It is about the angle of reflection

(b) It is the angle of incident at which no reflections occur

(c) It is the angle of incident at which maximum reflections occur

(d) It is about the angle of refraction

I had been asked this question at a job interview.

My query is from Radio Wave Propagation in chapter Radio Wave Propagation of Antennas

Answer 1

Right option is (b) It is the angle of incident at which no reflections occur

The explanation is: Brewster angle is defined as the angle of incident at which no reflections occurs.

\(θ=tan^{-1}⁡\sqrt{\frac{ϵ_{r2}}{ϵ_{r1}}} \)
