If the pressure amplitude in a sound wave is tripled, then by what factor the intensity of sound wave is increased?

A

`3`

B

`6`

C

`9`

D

`sqrt(3)`

Text Solution

Verified by Experts

The correct Answer is:
C
`I=p_(0)^(2)/(2 rho v)`
`I_(2)/I_(1)=[((p_(0))_(2))/((p_(0))_(1))]^(2)=(3)^(2)=9`

Sound Waves

Two sound waves one in air and the other in fresh water are equal in intensity. (a) Find the ratio of pressure amplitude of the wave in water to that of the wave in air. (b) If the pressure amplitudes of the waves are equal then what will be the ratio of the intensities of the waves. [ V_(sound) = 340 m//s in air & density of air = 1.25 kg//m^(3), V_(sound) = 1530 m//s in water, density of water = 1000 kg//m^(3) ]
