1.	The range of frequencies handled by the waveguides is in(a) Hz(b) KHz(c) MHz(d) GHzI have been asked this question during a job interview.Origin of the question is Types of Transmission Lines in section Transmission Lines of Electromagnetic Theory
Answer» Correct ANSWER is (d) GHz The best EXPLANATION: The waveguides are operated in the GHz range. In particular, the waveguides are ACTIVE above 6 GHz. The range goes upto several tens of GHz. Beyond this range, the transmission is HANDLED by OPTIC fibre cables.
