Question

In which of the following medium will sound travel the fastest?

• A. Solid
• B. Both solid and liquid
• C. Liquid
• D. Gas

Answer 1

The correct option is A

Solid

The explanation for the correct option:

Solid:

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. Thus, in steel sound travels the fastest $\left(5100m/s\right)$.

The explanation for incorrect options:

1. The speed of sound in a gas is around $340m/s$ and in liquid is $1480m/s$.

Hence, option (a) is correct.
