SUMMARY
The formula for finding the lines of maxima and minima in wave interference, n(lambda) = d sin(theta), applies to diffraction gratings due to the principle of superposition. Each pair of slits in a diffraction grating behaves similarly to the two-slit interference model, producing constructive and destructive interference patterns. The integer n represents the order of the maxima, while lambda denotes the wavelength of the light. The spacing d is the distance between adjacent slits in the grating, confirming that the same formula governs both two-slit and multi-slit interference phenomena.
