Assertion: Two point coherent sources of light 
and 
are placed on a line as shown. 
and 
are two points on that line. If at point 
maximum intensity is observed then maximum intensity should also be observed at 
.
Reason: In the figure of assertion the distance 
is equal to distance 
.
Text Solution
Verified by ExpertsThe correct answer is:
B
If maximum intensity is observed at 
then for maximum intensity to be also observed at 
and 
must have phase difference of 
(where 
is an integer).
