If is the intensity of the principal maximum in the single slit diffraction pattern, then what will be its intensity when the slit width is doubled ?
As we learnt in
Intensity of Diffracted light -
- wherein
Where
For diffraction pattern
Where denotes path difference For principal maxima = 0
Hence
Hence intensity remains constant at
