Q1:

A plane EM wave is travelling in an unbound loss less dielectric having μy = 1 and εy = 4, the time average Poynting vector of the wave is 5 W/m3 . The phase velocity vp (assuming velocity of light as 3 x 108 m/sec) is

A 1.5 x 108 m/sec

B 3 x 108 m/sec

C 2.5 x 108 m/sec

D 0.5 x 108 m/sec

ANS:A - 1.5 x 108 m/sec
