Two sources A and B vibrate with the same amplitude. They produce sounds of frequencies 1kHz and 30kHz respectively. Which of the two waves will have larger power? `(AS_1)`

Two tuning forks vibrate with the same amplitude but the frequency of the first is double the frequency of the second. Which fork produces more intense sound in air ?

Two sound waves produce 12 beats in 4 second. By how much do their frequencies differ ?

Two sound waves, originating from the same source, travel along different paths in air and then meet at a point. If the source vibrates at a frequency of 1.0 kHz and one path is 83 cm longer than the other, what will be the nature of interference? The speed of sound in air is 332 ms^-1 .

Two sound waves moves in the same direction in the same medium. The pressure amplutides 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 P_1 and that by the second wave be P_2 then.

Two sound waves travel in the same direction in a medium . The amplitude of each wave is A and the phase difference between the two waves is 120^(@) . The resultant amplitude will be :
