A tuning fork whose frequency as given by manufacturer is 512 Hz is being tested with an accurate oscillator it is found that the fork produces a 2 beat per sound when oscillator reads 514 Hz and 6 beat per sound when it reads 510 Hz. The actual frequency of fork is

Vibrating tuning fork of frequency n is placed near the open end of a long cylindrical tube. The tube has a side opening and is fitted with a movable reflecting piston. As the piston is moved through 8.75 cm, the intensity of sound changes from a maximum to minimum. If the speed of sound is 350 m/s. Then n is

Two loudspeakers L1 and L2 driven by a common oscillator and amplifier, are arranged as shown. The frequency of the oscillator is gradually increased from zero and the detector at D records a series of maxima and minima. If the speed of sound is 330 ms^−1 then the frequency at which the first maximum is observed is :

In a Hall, a person receives direct sound waves from a source 120 m away. He also receives a wave from the same source which reaches him after being reflected from the 25 m high ceiling at a point halfway between them. The two waves interfere constructively for wavelengths (in meters)
