Two coherent point source of frequency (...


Two coherent point source of frequency (`f=(10v)/(d)` where v is speed of light) are placed at a distance d apart as shown in figure. The receiver is free to move along the dotted line shown in the figure. Find total number of maximum observed by receiver

A

6

B

7

C

5

D

8

Text Solution

Verified by Experts

The correct Answer is:
A
`flamda=v=(10lamdav)/(d)implieslamda=(d)/(10)`
Maximum path diff. can be `(d)/(3)` Hence, number of maximum will be 6.
