Question

The velocity of electromagnetic wave is parallel to

विकल्प

• `vecB xx vecE`

• `vecE xx vecB`

• `vecE`

• `vecB`

Answer 1

`vecB`

Explanation:

Electromagnetic waves have a velocity that is perpendicular to both the electric field vector `vecE` and the magnetic field vector `vecB`, and its direction can be determined using the right-hand rule.
