Which of the above two graphs (a) and (b) (Fig.12.3) representing the human voice is likely to be the male voice? Give reason for your answer.

Answers (1)

The difference between human male voice and female voice is on the basis of pitch or frequency.

Male voice will have lower frequency in comparison with female voice.

We know that frequency is inverse of time period of oscillation.

f=\frac{1}{T}

In the given graph, it is quite visible that time period of graph (a) is more than time period of graph (b).

Therefore graph (a)  must be corresponding to male voice.
