Question

An EM wave is propagating in a medium with a velocity V → = V 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, - y direction, + z direction, - z direction, - x direction

MARKS App · Accepted Answer

V ^ = E ^ × B ^ , i ^ = j ^ × k ^ ∴ B ^ = k ^ , + z direction
