The displacement time graph for two sound waves A and B are shown in the figure. Then the ratio of their intensities `I_(A)//I_(B)` is equal to

A

`1:4`

B

`1:16`

C

`1:2`

D

`1:1`

Text Solution

Verified by Experts

The correct Answer is:
D
`I=2pi^(2)n^(2)A^(2)rhovimplies(I_(1))/(I_(2))=((A_(1)n_(1))/(A_(2)n_(2)))^(2)=((2)/(1)xx(1)/(2))^(2)=1:1`
