The product of the phase and the group velocities is given by the(a) S

1.	The product of the phase and the group velocities is given by the(a) Speed of light(b) Speed of light/2(c) 2 x Speed of light(d) (speed of light)/4The question was posed to me during an internship interview.Query is from Phase and Group Velocity in portion Waveguides of Electromagnetic Theory
Answer» Correct choice is (d) (speed of light)/4 Best EXPLANATION: The product of the phase and the GROUP VELOCITIES is given by the square of the speed of the light. THUS Vp X Vg = c^2 is the relation.
