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?`
