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

Answers (1)

Hence, the correct answer is Graph (a).

Explanation:-

The difference between the human male voice and the 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 the time period of oscillation.

so, 

f=\frac{1}{T}

hence,

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