What is the direction of propagation of the wave if e⃗ =ei^,b⃗ =−bj^. express the direction of the propagation vector, p⃗ , as a unit vector. its three components should be entered in order (x, y,z) separated by commas. for example, if the wave propagates only in the -x direction, enter -1,0,0.

Answer with Explanation:

We are given that

Electric field vector=

Magnetic field vector=

We have to find the direction of propagation of the wave.

We know that  

The direction of propagation of wave=

The direction of propagation of wave=

Because ()

The  wave propagate in -z direction.

Therefore, the component of the vector is (0,0,-1).

Hence, the direction of the propagation of wave is - z direction and component of direction of propagation vector is (0,0,-1).
