Question

Why is sound a wave?

Answer 1

Sound:

1. Sound is basically generated due to vibrations.
2. The vibrations cause surrounding particles to further vibrate due to the transmission of pressure energy.
3. This disturbance creates some back and forth vibration in the surrounding particles as it propagates.
4. This propagation of pressure energy due to vibration is transverse in nature, making it a transverse mechanical wave.

These reasons explain why sound is considered a wave.
