Question

The oscillating magnetic field in a plane electromagnetic wave is given by



By= ( 8 x 10-6) sin ( 2 x 1011 t + 300πx ) Τ



1)Calculate the wavelength of the electromagnetic wave

2)The direction of electric field and direction of propagation of the

electromagnetic wave?

Answer 1

here magnetic field is along negative Y axis so direction of electric field will be negative Z axis
and the hence the wave is propagating in negative X direction.
