उत्तर
(i) The diagram (i) represents the fundamental note because its frequency is lowest and amplitude maximum.
(ii) The diagram: (ii) represents the sound note having frequency four times that of the (i) or fundamental.
(iii) The frequency: (ii) is two times the frequency of (i) so the ratio between the frequencies of (i) and (ii) is 1: 2.
