An `EM` wave is propagating in a medium whith a velocity `vecv=vhati`. The instantaneous oscillating electric field of this of em wave is along `+y` axis. Then the direction of oscillating magnetic field of the `EM` wave will be along

A

`-y` direction

B

`-x` direction

C

`+z` direction

D

`-z` direction

Text Solution

Verified by Experts

The correct Answer is:
C
For `EM` wave `vec(E)xxvec(B)=vec(v)`
`(Ehatj)xxvec(B)=vi`
`:. vec(B)=Bhatk`
