The two interfering waves have intensities in the ratio `9 : 4`. The ratio of intensities of maxima and minima in the interference pattern will be

A

`1:25`

B

`25:1`

C

`9:4`

D

`4:9`

Text Solution

Verified by Experts

The correct Answer is:
B
`(I_(max))/(I_(min))=((sqrt(I_(1))+sqrt(I_(2)))/(sqrt(I_(1))-sqrt(I_(2))))^(2)=((sqrt(9)+sqrt(4))/(sqrt(9)-sqrt(4)))^(2)=(25)/(1)`
