Question

Velocity of sound in air is :

• A. slower in dry air than in moist air
• B. directly proportional to pressure
• C. directly proportional to humidity
• D. faster in dry air than in moist air

Answer 1

The correct option is C

directly proportional to humidity

Sound can propagate faster in the medium of less denser air. The density of air decreases with increase in humidity. So,the velocity of sound increases with the increase in humidity.
