Air temperature in the Rajasthan deserrt can reach `46^(@)C`. What is the velocity of sound in air at that temperature ? `(V_(0)=331ms^(-1))`.

(a) Air temperature in the Rajasthan desert can reach 46^(@)C . What is the velocity of sound in air at that temperature ? (V_(0)=331ms^(-1)) . (b) A sound wave has a frequency of 200 Hz and a speed of 400ms^(-1) in a medium. Find the wavelength of the sound wave.

At what tempreature will the velocity of sound in air be double the velocity of sound in air at 0^(@)C ?

The velocity of sound changes by ________ when the temperature changes by 1^@C .

On increasing the temperature, the speed of sound in air:
