and a width of 
. The number of bright fringes between the first and the second diffraction minima is:
Text Solution
Verified by ExpertsThe correct answer is:
B
For diffraction
Location of 
minima
Location of 
minima
Now for interference
Path for interference
Path difference at 
.
Path difference at 
.
So orders of maxima in between 
and 
is
So 5 bright fringes all present between 
.
