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 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 .

Figure shows a source of sound moving along the X-axis at a speed of 22 m s^-1 continuously emitting a sound of frequency 2.0 kHz which travels in air at a speed of 330 in s^-1 . A listener Q stands on the Y-axis at a distance of 330 m from the origin. At t = 0, the source crosses the origin P. (a) When does the sound emitted from the source at P reach the listener Q 9 (b) What will be the frequency heard by the listener at. this instant 9 (c) Where will the source be at this instant ? .

A woman is traveling in a car at a speed of 25m/s . She is moving away from a source producing a sound of 512 Hz .Calculate the frequency of sound heard by ner .(Speed of sound in air= 340 m/s )

A source of sound emitting sound with frequency 540Hz approaches a staionary observer with a speed of 30 ms^-1 . If velocity of sound is taken as 330 ms^-1 , the frequency as heard by the observer will be

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)
