The electric field part of an electromagnetic wave in a medium is represented by Ex = 0; \(E_{y}=2.5 \frac{\mathrm{N}}{\mathrm{C}} \cos \left[\left(2 \pi \times 10^{6} \frac{\mathrm{rad}}{\mathrm{m}}\right) t-\left(\pi \times 10^{-2} \frac{\mathrm{rad}}{\mathrm{s}}\right) x\right]\) ; 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 300 m
- moving along y-direction with frequency \(2 \pi \times 10^{6}\) Hz and wavelength 200 m
Answer
(B) moving along x-direction with frequency 10 6 Hz and wavelength 200 m
