Question
Air temperature in the Rajasthan desert can reach 46°C. What is the velocity of sound in air at that temperature? (V0= 331 ms–1)

Solution
Velocity of sound, v0 = 331 ms-1
Air temperature, T = 46° C
Velocity of sound in air temperature vT = (v0 + 0.61T) ms-1
= 331 + (0.61 × 46)
= 331 + 28.06
vT = 359.06 ms-1.
