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