All ISRO Electronics & Communication (ECE) papers | ISRO Electronics & Communication (ECE) 2013

Topic: Electromagnetics

For non dispersive medium

  • A. Phase velocity > Group velocity
  • B. Phase velocity < Group velocity
  • C. Phase velocity = Group velocity
  • D. non of the above

Answer: C. Phase velocity = Group velocity

Explanation: In non-dispersive media, the speed of wave is independent of frequency. Thus, both the phase velocity and group velocity are same.
