A plane electromagnetic wave having a frequency v = 23.9 GHz propagates along the positive z-direction in free space. The peak value of the Electric Field is 60 V/m. Which among the following is the acceptable magnetic field component in the electromagnetic wave ?
(1) vector B = 2 x 10–7 sin(1.5 x 102 x + 0.5 x 1011t) j
(2) vector B = 60 sin(0.5 x 103 x + 1.5 × 1011t) k
(3) vector B = 2 x 10–7 sin(0.5 x 103 z + 1.5 × 1011t) i
(4) vector B = 2 x 10–7 sin(0.5 x 103 z – 1.5 × 1011t) i
