An em wave is propagating in a medium with a velocity . 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
As we have learned
Poynting Vector -
- wherein
It is total energy flowing perpendicularly per second per unit area into the surface in free space.
Option 1)
— y direction
This is incorrect
Option 2)
+ z direction
This is correct
Option 3)
— z direction
This is incorrect
Option 4)
— x direction
This is incorrect
