I was working on derivation to find the witdh of principle maxima in n slit diffraction
Angular width=2Δθm=2λ/(Ndcosθm)
Where d:distance between slits
θm:angle at which mth order principle maxima is present.
N:no. Of slits
#in the diagram given below why the minima just adjacent to mth pricinple maxima is written as mN±1
*the thing I know is that this mN±1 is related to the fact that there are N-1 minimas present b/w 2 consecutive principle maximas
How that I 'm not able to relate it?
