Electromagnetic Waves Ques 10
10. The oscillating electric and magnetic field vectors of electromagnetic wave are oriented along
[1994]
(a) the same direction and in phase
(b) the same direction but have a phase difference of $90^{\circ}$
(c) mutually perpendicular directions and are in phase
(d) mutually perpendicular directions but has a phase difference of $90^{\circ}$
Show Answer
Answer:
Correct Answer: 10.(c)
Solution:
- (c) The direction of oscillations of $E$ and $B$ fields are perpendicular to each other as well as to the direction of propagation. So, electromagnetic waves are transverse in nature.
The electric and magnetic fields oscillate in same phase.
