`S_1 , S_2` are two coherent sources (having initial phase difference zero ) of sound located along x - axis separated by `4lamda` Where is `lamda` wavelength of sound emitted by them . Number of maxima location on the elliptical boundary around it will be : [ `S_1 and S_2` are assumed to be at focus of ellipse ]

A

`16`

B

`12`

C

`8`

D

`4`

Text Solution

Verified by Experts

The correct Answer is:
A

AT `B` Path difference is `O` and at `A` path difference is `4lambda`. From `nlambda` there are `3` maxima position between `A` & `B`. So total maxima in ellipse `= 16`
Note `rarr` if there were circle, rectangle, square instead of ellipse answer is same.
