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

A source emits sound of frequency 600 Hz inside water. The frequency heard in air will be

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 car is moving with a speed of 72 "km-hour"^(-1) towards a roadside source that emits sound at a frequency of 850 Hz. The car driver listens to the sound while approaching the source and again while moving away from the source after crossing it. If the velocity of sound is 340 ms^(-1) , the difference of the two frequencies, the driver hears is

A source whistling a sound of frequency 450 Hz moves towards a stationary listener with a speed of 33 m/s. If velocity of sound is 333 m/s, then find frequency of sound heard by this listener.

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 .

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 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?
