The oscillating electric and magnetic vectors of an electromagnetic wave are oriented along

A

The same direction but differ in phase by `90^(@)`

B

The same direction and are in phase

C

Mutually perpendicular direction and are in phase

D

Mutually perpendicular and differ in phase by `90^(@)`

Text Solution

Verified by Experts

The correct Answer is:
c
`vecE` and `vecB` are mutually perpendicular to each other and are in phase i.e, they become zero and minimum at the same place and at the same time.
