two sound waves moves in the same direction .if the average power transmiitted across a cross - section by them are equal while their wavelengths are in the ratio of 1:2 . Their pressure amplitudes would be in the ratio of

Text Solution

Verified by Experts

The correct Answer is:
1
Pressure amplitude is given as
`DeltaP_(0) = sqrt(2PIv)`
As P.I and v are same for both waves so their pressure amplitudes will be equal.
