Electromagnetic waves
Electromagnetic waves are those waves in which there are sinusoidal variations of electric and magnetic fields at right angle to each other as well as right angle to the direction of propagation. The ratio of electric vector and magnetic vector gives the velocity of light and `vecExxvecB` gives the direction of propagation of electromagnetic wave.
If `vecE` and `vecB` represent electric and magnetic field vectors of the electromagnetic wave, the direction of propagation of electromagnetic wave is along.

A

`E/2`

B

2E

C

`E/(sqrt2)`

D

`sqrt2E`.
