Unlock the secrets of light diffraction with our free online Diffraction Grating Calculator. Quickly determine the diffraction angle, wavelength of light, grating spacing, or order of maximum using the fundamental grating equation `d sin(θ) = mλ`. This tool is perfect for students, educators, and professionals in optics and physics.
Formula:
The Diffraction Grating Calculator uses the fundamental grating equation:
d sin(θ) = mλ
Where:
d= distance between adjacent slits (grating spacing)θ= angle of diffraction (angular separation from the central maximum)m= order of the maximum (an integer, e.g., 0 for central, 1 for first-order, etc.)λ= wavelength of the light
When calculating the angle of diffraction (θ), the formula is rearranged to: θ = arcsin(mλ / d)
