1 Electromagnetic Waves
A plane electromagnetic wave of frequency 20 MHz travels through a space along x direction. If the electric field vector at a certain point in space is 6 V m−1, what is the magnetic field vector at that point? 1) 2×10−8T 2) 1/ 2×10−8T 3) 2T 4) 1 / 2T
Velocity of EM wave $$v = 3\times 10^{8}$$ $$m/s$$
