A plane EM wave is propagating along x direction. It has a wavelength of 4 mm. If electric field is in y direction with the maximum magnitude of 60 Vm–1, the equation for magnetic field is:
1
\(\rm B_z = 60 sin\left[\frac{\pi}{2}\left(x-3\times10^8t\right)\right]\hat{k}T\,\)
2
\(\rm B_z = 2\times10^{-7} sin\left[\frac{\pi}{2}\times10^3\left(x-3\times10^8t\right)\right]\hat{k}T\,\)
3
\(\rm B_x = 60 sin\left[\frac{\pi}{2}\left(x-3\times10^8t\right)\right]\hat{i}T\,\)
4
\(\rm B_z = 2\times10^{-7} sin\left[\frac{\pi}{2}\left(x-3\times10^8t\right)\right]\hat{k}T\,\)
