The speed of sound in air does not depend on
Correct answer: B. Pressure
- A. Density of medium
- B. Pressure
- C. Temperature
- D. Moisture
Explanation
Speed of sound increases with increase in temperature. But it does not depend upon pressure.

About Speed of Sound
The speed of sound depends on the properties of the medium, including its elasticity and density, and in gases it varies mainly with temperature. Questions connect speed with frequency and wavelength, compare sound in solids, liquids and gases, and distinguish the speed of propagation from the oscillating particles' motion.
