A narrow sound pulse (for example, a short pip by a whistle) is sent across a medium. (a) Does the pulse have a definite (i) wavelength, (ii) frequency, (iii) speed of propagation ? (b) If the pulse rate is `1` after every `20 s`, (i.e. the whistle is blown for a split second after every `20 s`) is the frequency of the note produced by the whistle equal to `(1)/(20) = 0.05 Hz` ?

Text Solution

Verified by Experts

The correct Answer is:
The pulse does not have a definite wavelength or frequency but has a definite speed of propagation (in a non-dispersive medium) (b) No.

A narrow sound pulse (for example, short pip by a whistle ) is sent across a medium. (a) Does the pulse have a definite (i) wavelength (ii) frequency (iii) speed of propagation. (b) If the pulse rate is 1 after every 20s, i.e. the whistle is blown for a split second after every 20 second, is the frequency of the note produced by the whistle equal to 1//20=0.05Hz?

A narrow pulse (for example, a short pip by a whistle) is sent across a medium. If the pulse rate is 1 after every 20 s (that is the whistle is blow for a split of second after every 20 s). Is the frequency of the note produced by the whistle equal to 1//20 or 0.05 Hz ?

The engine of a train sound a whistle at frequency v, the frequency heard by a passenger is

An observer on a railway platform noticed that when a train passed through the station, at a speed of 72 kg h^(-1) , the frequency of the whistle appeared to drop by 500 Hz. Calculate the actual frequency of the note produced by the whistle. Velocity of sound in air = 340 ms^(-1) .

A: When a narrow pulse of light is sent through a medium, it doesn't retain its shape as it travels through the medium. R: Since the speed of propagation in a medium depends on wavelength , different wavelength components of the pulse travel with different speeds.

A train, blowing a whistle of frequency f, is standing in the railway yard A person is running towards the engine. The frequency of the sound of the whistle as heard by the person will be

A fire whistle emits a tone of 170 Hz. Take the speed of sound in air to be 340 m/s. The wavelength of this sound is about
