Question

In waveguides, which of the following conditions will be true? (a) V > c (b) V < c (c) V = c (d) V >> c I had been asked this question during an internship interview.

Answer 1

Right choice is (a) V > c To elaborate: In waveguides, the phase velocity will always be greater than the speed of light. This enables the wave to propagate through the waveguide. Thus V > c is the required condition.
