1.	The phase velocity of a wave having a group velocity of 6 x 10^6 is (in order of 10^8 m/s)(a) 2.4(b) 3(c) 15(d) 150This question was addressed to me by my college professor while I was bunking the class.This question is from Phase and Group Velocity topic in chapter Waveguides of Electromagnetic Theory
Answer» The correct OPTION is (d) 150 For EXPLANATION: We KNOW that the phase and the group velocities are GIVEN by Vp x Vg = c^2. On SUBSTITUTING for Vg = 6 x 10^6 and the speed of light, we get Vp = 150 x 10^8 m/s.
