Question

The nature of sound waves is :

• A. Transverse
• B. Longitudinal
• C. Electromagnetic
• D. Seismic

Answer 1

The correct option is B

Longitudinal

Correct option is B: Longitudinal

Step1: Explanation for the correct answer

1. Longitudinal Wave: A wave motion in which the particles of the medium vibrate about their mean position along the direction of propagation of the wave is called longitudinal wave motion.
2. In the case of sound waves, medium particles vibrate in the direction of wave propagation so it is a Longitudinal wave.

Step 2: Explanation for incorrect answer

1. Transverse wave: A wave motion in which an individual particle of the medium vibrates in a direction at right angles to the direction of propagation of the wave is called transverse wave motion
2. Electromagnetic waves are Transverse waves and seismic waves are longitudinal in nature.

Hence, option (B) is correct.
