The intensity of the primary maximum in a two-slit interference pattern is given by 1, and the intensity of the primary maximum in a three-slit interference pat

The intensity of the primary maximum in a two-slit interference pattern is given by 1, and the intensity of the primary maximum in a three-slit interference pattern is given by I,. Assuming the far-field approximation, same slit parameters and intensity of the incident light in both the cases , and I, are related as (B) (A) (C) - (D) nASA
