Q. 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 along

Solution:

$\vec{E} \times \vec{B} = \vec{V}$
$(E \hat{j}) \times (\vec{B}) = V \hat{i}$
So, $\vec{B} = B \hat{k}$
Direction of propagation is along $+z$ direction.
