Does the waveguide with dimensions 3 cm x 5.5 cm exist?

A. Yes

B. No

This question was addressed to me by my college director while I was bunking the class.

I want to ask this question from Transverse Electric Waves(TE) topic in portion Waveguides of Electromagnetic Theory

The correct answer is B. No

For explanation: For a waveguide, the dimension a should be greater than b. Here a = 3 and b = 5.5, thus such waveguide does not exist.
