The electric field part of an electromagnetic wave in a medium is represented by Ex = 0,
\(E_{y}=2.5 \frac{\mathrm{~N}}{\mathrm{C}} \cos \left[\left(2 \pi \times 10^{6} \frac{\mathrm{rad}}{\mathrm{~s}}\right) t-\left(\pi \times 10^{-2} \frac{\mathrm{rad}}{\mathrm{~m}}\right) x\right]\),
Ez = 0. The wave is
- moving along x direction with frequency 106 Hz and wavelength 100 m
- moving along x direction with frequency 106 Hz and wavelength 200 m
- moving along –x direction with frequency 106 Hz and wavelength 200 m
- moving along y direction with frequency 2p × 106 Hz and wavelength 200 m
Answer
(B) moving along x direction with frequency 10 6 Hz and wavelength 200 m
