WebOct 31, 2024 · The grating equation you've used is correct, and in order to find the first order diffraction angle ( n = 1) you need to use arcsine trigonometric function and carefully place data with respective units: (1) n λ = d sin Θ (2) d = 1 m m N [ m m] where N is number of lines per unit length. WebThis leads to The Grating Equation: (1) n λ = d ( sin α + sin β) with the sign convention as noted. n is the diffraction order and says by how many wavelengths the wavefront shifts between incidence and scattering. If the grating acts as a mirror, n = 0.
