An EM were is propogating in a medium with a velocity `v=vhat(i)`. The instantaneous oscillating electric field of this EM wave is along `+y axis`. Then, the direction of oscillating magnetic field of EM wave will be along

A

`-y` direction

B

`+z` direction

C

`-z` direction

D

`-x` direction

Text Solution

Verified by Experts

The correct Answer is:
B
`vec E xx vecB=vecV`
`(Ehat j)xxvec (B)=V hat i`
So,` vecB=Bhat K`
Direction of propagation is along +z direction.
