Question

The velocity of sound waves in a medium does not depend on

• A. temperature
• B. pressure
• C. humidity
• D. direction of air

Answer 1

Answer: (B)

Speed of sound does not depend on pressure, since at the constant temperature,
$=\frac{\text{pressure}}{\text{density of medium}}=$ constant
Whereas speed of sound depends on the variation to temperature, humadity and flow of the medium.
