Question

Explain Amplitude
Define sound frequency

Answer 1

amplitude is the maximum displacement or distance moved by appointment on a vibrating body or wave measured from its equilibrium position.
it is the property of sound that determines its pitch. the S.I unit of sound frequency is hertz.

Answer 2

Heya friend!
Rajdeep here....

Here's your answer:
Amplitude of a sound is the maximum displacement of the sound wave from its mean position. The loudness of sound depends on the square of the amplitude.

Frequency of a sound is the number of oscillations or vibrations made by the sound wave in one time period. Pitch of the sound depends upon frequency. SI unit of frequency is Hertz (Hz), where 1kHz = 1000Hz.

Thanks!!
