A sinusoidal electromagnetic wave is propagating in vacuum. At a given point and at a particular time the electric field is in the x direction and the magnetic field is in the -y direction. What is the direction of propagation of the wave

Respuesta :

Answer:

Explanation:

A wave is a disturbance or oscillation that passes through spatial time and is followed by a transfer of energy. For transverse waves, the propagation direction is perpendicular to the oscillation direction. A wave moves energy rather than moving mass within the direction of propagation.

From the given information;

The direction = [tex]E^{\to}\times B^{\to}[/tex]

This implies that:  [tex]\hat i \times (-j)[/tex]

[tex]\implies - \hat k[/tex]

In the [tex]-z[/tex] direction
