Q1:

Which of the following statement regarding waveguides is incorrect?

A At waveguide can be coupled to a coaxial cable

B At frequencies below the cut off value the wave progresses across the waveguide after total reflections

C Waveguides are usually air filled hollow conducting metallic tubes for transmitting UHF and microwaves

D Waveguides can handle large power at UHF and microwaves

ANS:A - At waveguide can be coupled to a coaxial cable

Here, Option B is incorrect since the waveguide is a high pass filter.
