The ratio of the intensities of two wave...

The ratio of the intensities of two waves is `16:9`. The ratio of their amplitudes is

A

`4:3`

B

`3:4`

C

`1:2`

D

`2:1`

Text Solution

Verified by Experts

The correct Answer is:
A
We know that `I prop a^(2) rArr a prop sqrt(I)`
`therefore (a_(1))/(a_(2))=sqrt((16)/(9))=(4)/(3)`
