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

`2:3`

B

`16:81`

C

`25:169`

D

`25:1`

Text Solution

Verified by Experts

`I_(1)/I_(2) = 9/4`
`I_("max")/I_("min") = (sqrt(I_(1)) + sqrt(I_(2)))^(2)/(sqrt(I_(1)) - sqrt(I_(2)))^(2) = 25:1`
