An EM wave is propagating in a medium with a velocity $$\overrightarrow{{v}}={v} \hat{i}$$. The instantaneous oscillating electric field of this EM wave is along the $$+y$$ axis. The direction of the oscillating magnetic field of the EM wave will be along:
1. $$-z \text-$$direction
2. $$+z \text-$$ direction
3. $$-y \text-$$ direction
4. $$+y \text-$$ direction
