A plane electromagnetic wave of frequency 20 MHz travels in free space along the +x direction. At a particular point in space and time, the electric field vector of the wave is Ey = 9.3 Vm–1 . Then, the magnetic field vector of the wave at that point is-
1
Bz = 9.3 × 10–8 T
2
Bz = 1.55 × 10–8 T
3
Bz = 6.2 × 10–8 T
4
Bz = 3.1 × 10–8 T
