Question

Velocity of sound in air is about

• A. 330 m/s
• B. 360 m/s
• C. 380 m/s
• D. 400 m/s

Answer 1

The correct option is A

330 m/s

Explanation:

1. The speed depends upon the factors such as pressure, temperature, and elasticity of the medium.
2. Hence, the sound wave travels fastest in solids, comparatively slower in liquids, and slowest in gases.
3. Sound waves travel with finite speed.
4. The speed of sound in air is around 330 m/s.

Hence, option (a) is correct.
