An EM wave is propagating in a medium with a velocity $\vec{V} = V \hat{i}$ . The instantaneous oscillating electric field of this em wave is along $+ y$ axis. Then the direction of oscillating magnetic field of the EM wave will be alongNEET 2018

Options:

Answer:

Solution:

$\hat{V} = \hat{E} \times \hat{B}$ , $\hat{i} = \hat{j} \times \hat{k}$

$∴ \hat{B} = \hat{k}$ , $+ z$ direction
