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 sound source, fixed at the origin, is continuously emitting sound at a frequency of 660 Hz. The sound travels in air at a speed of 330 ms^-1 . A listener is moving along the line x = 336 m at a constant speed of 26 m Find the frequency of the sound as observed by the listener when he is a. at y=-140m, b. at y=0 and c. at y=140m .

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

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

A source producing a sound of frequency 500 Hz is moving towards is listener with a velocity of 30 ms^(-1) . The speed of the sound is 330ms^(-1) . What will be the frequency heard by listener?

A siren emitting sound of frequency 800 Hz is going away from a static listener with a speed of 30 m/s. Frequency of the sound to be heard by the listener is (Take velocity of sound as 330 m/s)
