A pair of narrow, parallel slits separated by 0.240 mm are illuminated with the green component from a mercury vapor lamp (λ = 546.1 nm). The interference pattern is observed on a screen 1.27 m from the plane of the parallel slits.
a) Compute the distance from the central maximum to the first bright region on either side of the central maximum.
b) Compute the distance among the first and second dark bands in the interference pattern.
