Question

The oscillating electric and magnetic field vectors of an electromagnetic waves far away from source are oriented along 

(A) Mutually perpendicular direction and differ in phase by 90° 

(B) Mutually perpendicular and in same phase 

(C) In same direction and in same phase 

(D) In same direction and differ in phase by 90°

Answer 1

The correct option is (B) Mutually perpendicular and in same phase.

Explanation:

Electric and magnetic field vectors are always in phase and are mutually perpendicular.
