Question

list the three characteristics of a sound wave and state the factors on which these depends.

Answer 1

#Amplitude of sound: Amplitude of sound is the maximum displacement of sound wave from its mean position.

#Loudness is a measure of response of our ear to sound. The unit of loudness is decibel. It depends on amplitude. If the amplitude is high, the loudness also will be high.

#Pitch is the characteristic of sound which help us to distinguish sounds ofsame loudness but of different frequency . It depends on frequency.

#hope its help you

Answer 2

There are 3 characterists of sound

1) Loudness - loudness of sound depends on amplitude of vibration of vibrating body.

2) Pitch- This is the property of sound which differentiate between different sound of same loudness.

3) Quality - The property of sound which enables us to differentiate between sound produced by different sound producing object.
