Question

Which of the following is likely to have a minimum frequency?
A. baby girl
B. a women
C. a man
D. a boy

Answer 1

Hint: Frequency is the number of times an event occurs per unit time. Since sound waves are sinusoidal they have frequency. And pitch is a property of sound which describes the loudness of the sound.
Here we can identify the answer by discussing the pitch and the frequency of the given options.

Complete step by step answer:
We know that frequency is the number of times an event occurs per unit time. More specifically, it is the count of the repeated event which occurs per unit time. And it is inversely proportional to the time period of the wave. With units as hertz or second inverse.
Whereas pitch is used to describe the nature of a sound wave. It is the major factor which distinguishes a noise from a melodic music.
Pitch is similar to frequency but it also depends on the psychology of the listener. Hence we can also say that frequency is directly proportional to pitch.
Generally the pitch of male decreases with age and the pitch of females increases with time. Then clearly, we can say that from the given options the male voice has the lowest pitch. Since frequency is directly proportional to pitch, we can also say that the frequency of the male voice is the least.

So, the correct answer is “Option C”.

Note: We know that the sound waves are produced due to the vibration of the particles of the medium through which they propagate. Then we can define the amplitude and the frequency of the sound wave which are also their properties. Then we can say that the pitch is the auditory sensation of the sound waves which has some frequency.
