Constructive interference occurs when \(d \space sin \space \theta = m \lambda\) form = 0, ± 1, ±2,..., where d is the distance between the slits, θ is the angle relative to the incident direction, and m is the order of the interference.

Much of the modern-day application of slit interference uses not just two slits but many, approaching infinity for practical purposes. We start the analysis of multiple-slit interference by taking the results from our analysis of the double slit (N = 2) and extending it to configurations with numbers of slits.

The amplitude of the electromagnetic wave is correspondingly diminished to 1/N of the wave at the principal maxima, and the light intensity, being proportional to the square of the wave amplitude, is diminished to \(1/N^2\) of the intensity compared to the principal maxima.

(b) The pattern obtained for white light incident on a grating. The large distance between the red and violet ends of the rainbow produced from the white light indicates the potential this diffraction grating has as a spectroscopic tool.
