If `E` and `B` represent electric and magnetic field vectors of the electromagnetic wave, the direction of propagation of eletromagnetic wave is along.

Options

A. `vecE`
B. `vecB`
C. `vecBxxvecE`
D. `vecExxvecB`

Answer

D

Explanation

A changing electric field produces a changing magnetic field and vice versa which gives rise to a transverse wave known as electromagnetic wave. The time varying electric and magnetic fields are mutually perpendicular to each and also perpendicular to the direction of propagation of this wave. The electrion vector is responsible for the optical effects of an `EM` wave and is called the light vector
The direction of propagation of electromagnetic wave is perependicular to both electric field vector `(vecE)` and `(vecB)` magnetic field vector `B` i.e, inthe direction of `vecExxvecB`
Here electromagnetic wave is along the `z`-direction which is given by the cross product of `E` and `B`
