NEET Physics (general) MCQ Question
Which of the following statements about electromagnetic waves is correct?
The electric field and magnetic field in an electromagnetic wave are always in phase.
Electromagnetic waves can only propagate in a vacuum and not in any material medium.
The direction of propagation of an electromagnetic wave is always perpendicular to both the electric field and magnetic field.
The energy carried by an electromagnetic wave is solely dependent on its electric field component.
Correct Answer
Detailed Explanation
In an electromagnetic wave, the direction of propagation is indeed perpendicular to both the electric field and magnetic field, as indicated by their relationship in propagation directions. This aligns with the fundamental understanding of electromagnetic wave behavior.
