Question

Is the lower frequency of vibrations,the higher is the pitch

Answer 1

Pitch is the charactersitcs of a sound that depends on the frequency recieved by a human ear.

A sound of high frequency have high pitch.

A sound of low pitch have low frequncy.

Answer 2

No. The pitch of sound will depend on how soon a particle vibrates when a wave passes through it. It is also called the frequency of the wave.

It refers to how sooner does a pressure vary from high to low and vice versa?

The higher is the frequency, i.e., more vibrations, the higher there will be the pitch while the lower the frequency, i.e., less vibrations, the lower will be the pitch.

Now, we know that frequency is the reciprocal of time period, therefore higher the frequency, there will be more valleys and peaks within a certain time.

As sound waves travel at about the same speed irrespective of frequency, hence a high frequency will mean more valleys and peaks in a space of sound wave.

Alternately, a high-frequency wavelength will be shorter than that of low-frequency waves.
