At a certain instant in time, the electric field of an electromagnetic wave in free space points in the -z direction, and the magnetic field points in the y direction. In what direction is this wave traveling

Respuesta :

Answer:

Direction of wave traveling is +X direction.

Explanation:

Given :

Direction of electric field = [tex]-Z[/tex] direction

Direction of magnetic field = [tex]+Y[/tex] direction

We know that electromagnetic waves is transverse wave.

The direction of electric field and magnetic field are perpendicular to each other.

So we write,

 [tex]\vec E \times \vec B = \vec n[/tex]

Where [tex]\vec n =[/tex] direction of propagation.

Put the direction on above equation,

 [tex]-\vec k \times \vec j = \vec n[/tex]

  [tex]\vec n = \vec i[/tex]

From the right hand rule we can say that direction of wave propagation is +X direction.

Answer:

+X Direction
