The speed of sound in air is 332 m/s. The speed of sound at 22 degrees centigrade will be:
Correct answer: A. 345 m/s
- A. 345 m/s
- B. 340 m/s
- C. 350 m/s
- D. 330 m/s
Explanation
Use the shortcut formula: Vx = Vs + 0.61( T)Vx= 332+ 0.61 (22)Vx= 345

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.
