Question

Electric and magnetic fields of EM waves are:

• A. In the same phase and perpendicular
• B. In the same phase and not perpendicular
• C. Not in same phase but perpendicular
• D. Neither in same phase nor perpendicular

Hint:

E, B, and k are mutually perpendicular

Answer 1

The Correct Option is A

In EM waves, E and B fields are perpendicular to each other and to the direction of propagation, and they oscillate in phase.
