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 ?

Question

$\overrightarrow B $ = 2 × 10^–7 sin(1.5 × 10² x + 0.5 × 10¹¹t) $\widehat j$

$\overrightarrow B $ = 60 sin(0.5 × 10³x + 0.5 × 10¹¹t) $\widehat k$

$\overrightarrow B $ = 2 × 10^–7 sin(0.5 × 10³ z + 1.5 × 10¹¹t) $\widehat i$

$\overrightarrow B $ = 2 × 10^–7 sin(0.5 × 10³ z - 1.5 × 10¹¹t) $\widehat i$
