A source produces a sound of wavelength. `1.7 xx 10^-2 m`. If its velocity is `343.4 ms ^-1`, then find frequency of sound.

Two timpani (tunable drums) are played at the same time. One is correctly tuned so that when it is struck, sound is produced that has a wavelength of 2.20 m. The second produces sound with a wavelength of 2.08 m. If the speed of sound is 343 m/s, what beat frequency is heard?

The driver of a car travelling with speed 30ms^-1 towards a hill sounds a horn of frequency 600 Hz. If the velocity of sound in air is 330ms^-1 , the frequency of reflected sound as heard by driver is

A source of sound is moving away from an observer at rest with a velocity of 50 m s^(-1) . If the frequency of sound is 200 Hz , find the apparent frequency observed by the observer. (Take velocity of sound = 300 m s^(-1))

A source of sound and a listener are moving towards each other . The velocity of the source is 20 m s^(-1) and that of the observer is 15 m s^(-1) . If the velocity of sound is 340 m s^(-1) and its frequency is 640 Hz, find the apparent frequency of the sound .

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.
