Question

The velocity of sound is maximum in

• A. Water
• B. Oil
• C. air
• D. iron

Answer 1

The correct option is D

iron

Explanation for correct option:

1. The speed of sound is greatest in solids and decreases as it moves from solids to liquids and liquids to gases.
2. A vacuum cannot conduct sound.
3. Sound travels at different speeds depending on the medium through which it passes.
4. Through denser media, sound travels at a higher rate. The solid density is higher than the air, liquid, and vacuum densities.
5. The velocity of sound in Vacuum medium < Gas medium < Liquid medium < Solid medium.

Hence, Option(D) is correct.
