Displacement distance graph of two sound waves A and B, travelling in a medium, are as shown in the diagram below:

Study the two sound waves and compare their :
Amplitudes

Explanation

From figure, amplitude of wave A
`=20 cm ` and amplitude of wave B = 10 cm.
Therefore `=("Amplitude of wave A ")/(" amplitude of wave B") = (20)/(10 )=2 :1`
