A pair of narrow, parallel slits separated by a distance of 0.221mm is illuminated by the green component from a mercury vapour lamp of wavelength 546.4 nm. The interference pattern is observed on screen 1.39 m from the plane of the parallel slits.

a) Discover the distance from the central maximum to the first bright region on either side of the central maximum.

b) Discover the distance between the first and second bands in the interference pattern.
