Question

Electromagnetic waves are:

• A. Longitudinal in nature
• B. Mechanical waves
• C. Transverse waves
• D. Stationary waves

Hint:

In electromagnetic waves: \[ \vec E \perp \vec B \perp \text{Direction of propagation} \] Hence EM waves are transverse.

Answer 1

The Correct Option is C

Electromagnetic waves consist of:
• Oscillating electric field
• Oscillating magnetic field These fields oscillate: \[ \text{perpendicular to each other} \] and also perpendicular to the direction of propagation.
Thus electromagnetic waves are: \[ \text{transverse in nature} \]
Step 1: Analyze the options
• Longitudinal waves have oscillations parallel to direction of propagation.
• Mechanical waves require a material medium.
• Electromagnetic waves can travel in vacuum.
• Stationary waves do not transfer energy from one place to another. Hence electromagnetic waves are: \[ \text{transverse waves} \] Option analysis:
• Option (A): Incorrect
• Option (B): Incorrect
• Option (C): Correct
• Option (D): Incorrect Therefore: \[ \boxed{\text{(C)}} \]
