Two coherent light sources 
and 
are at a distance 
from each other ( 
wavelength). The distance from 
on the 
-axis at which the interference is constructive, is
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
C
Say 
be the point on 
-axis, where constructive interference is obtained.
x 
Further, 
Hence, the distance from 
on the 
-axis at which the interference is constructive is 
.
