Explain how Maxima and Minima occur in Young's double slit experiment

When coherent, in-phase light passes through two slits they act as seperate sources, these waves diffract and overlap, causing regions of constructive and destructive interference. When they collide with a screen maxima are produced when there is a (N) wavelength path difference, leading to constructive interference. Minima are produced when there is a (N+1/2) wavelenght path difference, so the waves have destructive interference
