A sound of frequency 5 Hz .

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 sound of frequency 600Hz inside water. The frequency heard in air will be equal to (velocity of sound in water =1500(m)/(s) , velocity of sound in air=300(m)/(s))

A sound source S, emitting a sound of frequency 400 Hz and a receiver R of mass m are at the same point. R is performing SHM with the help of a spring of force constant K. At a time t = 0, R is at the mean position and moving towards the right, as shown. At the same time, the source starts moving away from R with some acceleration a. The frequency registered by the receiver at a time t = 10 s is 250 Hz. What is the time (in seconds) at which the corresponding registered frequency of 250 Hz was emitted by the source? [Given that (m)/(K)=(25)/(pi^(2)) and amplitude of oscillation = (100)/(pi) m, V_("sound") = 320 m s^(-1)]

A source emitting sound at frequency 4000 Hz, is moving along the Y-axis with a speed of 22 m s^-1 . A listener is situated on the ground at the position (660 m, 0). Find the frequency of the sound received by the listener at the instant the source crosses the origin. Speed of sound in air = 330 m s^-1 .

.A source is moving with a constant speed of "10m/s" on a circular track of "200m" .It emits a sound of frequency "200Hz" .A listener stands at the centre of the circular track.The frequency recieved by the listener is (velocity of sound "=340m/s" ) 1) zero 2)200Hz 3)190Hz 4) 210Hz
