The velocity of electromagnetic wave is ...

The velocity of electromagnetic wave is parallel to

A

`vecB xx vecE `

B

`vecE xx vecR `

C

`vecE `

D

`vecB `

Text Solution

Verified by Experts

The correct Answer is:
B
According to Maxweel, the electromagnetic waves are those waves in which there are sinusoidal variation of electric and magnetic field vector at ritht angles to each other as well as the right angles to the direction of wave propagation .

If the electric field `(vecE)` and magnetic field `(vecB)` are vibrating aling Y and Z direction, propagation of electromagnetic wave will be along the X-axis. Therefore, hte velocity of electromagnetic wave is parallel to `vecE xx vecB.`
