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

Options

A. The same direction but differ in phase by `90^(@)`
B. The same direction and are in phase
C. Mutually perpendicular directions and are in phase
D. Mutually perpendicular directions and differ in phase by `90^(@)`

Answer

C

Explanation

`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.
