The temperature at which speed of sound in air becomes double its value at 0 degree C is

The intensity of a plane progressive wave of frequency 1000 Hz is 10^−10 Wm^−2. Given that the speed of sound is 330 m/s and density of air is 1.293 kg/m^3 . Then the maximum change in pressure in N/m^2 is The temperature at which speed of sound in air becomes double its value at 0 [...]

Two sound waves move in the same direction in the same medium. The pressure amplitudes of the waves are equal but the wavelength of the first wave is double the second. Let the average power transmitted across a cross section by the first wave be P1​ and that by the second wave be P2​. The [...]

A point source emits sound equally in all directions in a non-absorbing medium. Two point P and Q are at distance of 9 m and 25 m respectively from the source. The ratio of the amplitude of the waves at P and Q is : The temperature at which speed of sound in air becomes [...]
