A narrow sound pulse (for example,a short pipe by a whistle) is sent across a medium Does the pulse have a definite (i) frequency,(ii)wavelength,(iii)speed of propagation?

A narrow sound 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 blown 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 ?

Explain why ( or how ) the shape of a pulse gets distored during propagation in a dispersive medium.

Explain why (or how): The shape of a pulse gets distorted during propagation in a dispersive medium.

5 Let us list some of the factors, which could possibly influence the speed of wave propagation: (i) nature of the source (ii) direction of propagation. (iii) motion of the source and/or observer. (iv) wavelength. (v) intensity of the wave. On which of te factors, if any, does,depend?: the speed of light in a medium (say, glass or water)

A gas in equilibrium has uniform density and pressure throughout its volume. This is strictly true only if there are no external influences. A gas column under gravity, for example, does not have uniform density (and pressure). As you might expect, its density decreases with height. The precise dependence is given by the so-called 'law of atmospheres' n_2 = n_1 exp[-(mg)(H_2-H_1)/(kT)] where n_2,n_1 refer to number density at heights h_2 and h_1 respectively.Use this relation to derive the equation for sedimentation equilibrium of a suspension in a liquid column: n_2= n_1 exp[(-mgN_a)/(RT) (1-(rho)/(rho))(h_2-h_1)] where rho is the density of the suspended particle, and rho' that of surrounding medium. [N_A is Avogadro's number, and R the universal gas constant].

How is sound propagated ? Can it be propagated through vacuum ? out of solid, liquid and gas in which medium speed of sound is maximum and in which it is least minimum ?
