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

Find the time period of a source of a sound wave whose frequency is 400 Hz.

A source of sound gives 5 beats when sounded with another source of frequency 100 Hz. The second harmonic of the source together with a source of frequency 200 Hz gives 10 beats s^(-1) . What is the frequency of the source?

A source of sound emitting a 1200 Hz note travels along a straight line at a speed of 170 m s^-1 . A detector is placed at a distance of 200 m from the line of motion of the source. (a) Find the frequency of sound received by the detector at the instant when the source gets closest to it. (b) Find the distance between the source and the detector at the instant it detects the frequency 1200 Hz. Velocity of sound in air = 340 m s^-1 .

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.
