Diffraction Grating

Find the diffraction angles and the maximum order of a grating from its line density and the light's wavelength, free online.
À propos de cette calculatrice

A diffraction grating with line spacing d produces bright maxima at angles satisfying d·sin θ = mλ. Spacing d = 1 mm ÷ (lines per mm). The highest observable order is the largest m with mλ ≤ d.
