For this to occur, we need all four waves to be in phase, which means that Δ x has to be a full wavelength, giving us the same formula for bright fringes that we found for the double slit: (3.3.1) d sin θ = m λ, m = 0, ± 1, ± 2, ….
Webwhere m is the order of diffraction (usually –1), f is the grating line density or frequency (in lines/mm), c is the speed of light, and θ m is the angle of diffraction. The factor of 2 is included so that Eq. (1) accounts for all four grating bounces. Note that Δ depends only on the product of the wavelength and grating frequency, or ...
