If f is the frequency of electromagnetic wave, fc is cutoff frequency, then in a rectangular waveguide-A-attenuation is low when f > fcB-attenuation is low when f < fcC-attenuation is high when f < fcD-either (b) or (c)-A-attenuation is low when f > fc

Question

If f is the frequency of electromagnetic wave, fc is cutoff frequency, then in a rectangular waveguide-A-attenuation is low when f &gt; fcB-attenuation is low when f &lt; fcC-attenuation is high when f &lt; fcD-either (b) or (c)-A-attenuation is low when f &gt; fc

APTITUDE CRACK · Accepted Answer

A attenuation is low when f &gt; fc Wavelength should be less than cutoff wavelengths. Therefore frequency should be higher than cutoff frequency for minimum attenuation.
