1.	The phase and group velocities does not depend on which of the following?(a) Frequency(b) Wavelength(c) Phase constant(d) Attenuation constantThis question was posed to me in a job interview.My doubt is from Phase and Group Velocity topic in section Waveguides of Electromagnetic Theory
Answer» Right option is (d) ATTENUATION CONSTANT Easiest explanation: The phase and the group velocities are directly RELATED by the frequency, WAVELENGTH and the phase constant. It is INDEPENDENT of the attenuation constant.
