A sound detector is moving with a constant velocity towards a stationary sound source. The source emits a beep of sound of frequency f=262 Hz that propogates with speec c=330m/s. The detector detects the beep of sound over a distance L=78 m and registers a frequency f=275 Hz. Find thhe duration of the beep emitted by the source.

A source emits a sound of frequency of 400 Hz , but the listener hears it to be 390 Hz . Then

A wall is moving with constant velocity u towards a fixed source of sound of frequency f . The velocity of sound is v . The wavelength of the sound reflected by the wall is

A small source of sound oscillates in simple harmonic motion with an amplitude of 17 cm. A detector is placed along the line of motion of the source. The source emits a sound of frequency 800 Hz which travels at a speed of 340 ms^-1 If the width of the frequency band detected by the detector is 8 Hz, find the time period of the source.

A statinary observer receives a sound of frequency 2000 Hz. The variation of apparent frequency and time is shown. Find the speed of source, if velocity of sound is 300(m)/(s)

If an observer moves towards a stationary source of sound with a velocity of one tenth the velocity of sound, then the apparent increase in frequency will be

A source of sound of frequency 500 Hz is moving towards an observer with velocity 30 m/s . The speed of sound is 330 m/s . the frequency heard by the observer will be

A source emits sound with a frequency of 1000 Hz. It is moving at 20 m/s toward a stationary reflecting wall. If the speed of sound is 340 m/s an observer at rest directly behind the source hears a beat frequency of
