Why does intensity of Secondary maxima becomes less as compared to the central maximum.
Asked by Prakhar Tripathi | 12th Feb, 2014, 07:31: PM
The intensity of light of a secondary maximum goes on decreasing with the order of the maximum. It is because, the intensity of the central maximum is due to wavelets from all parts of the slit, the first secondary maximum is due to wavelets from one third part of the slit only, the second secondary maximum is due to the wavelets from the fifth part only and soon.
Hence, the intensity of secondary maxima becomes less as compared to central maximum.
