Question
In deriving the single slit diffraction pattern, it is observed that the intensity is zero at angle 
. In how many equal parts the slit may be divided to justify this observations ?
. In how many equal parts the slit may be divided to justify this observations ?Options

C.n
D.
Solution
For dark fringe sin θ = 
So, No. of part′s = n.
r1 = r2 = r
So, No. of part′s = n.
r1 = r2 = r
