Single Slit Diffraction Calculator

Calculate diffraction minima angles and positions for single slit experiments

Wavelength (nm):

Slit Width (μm):

Screen Distance (m):

Diffraction Order (m):

Single slit minima: a sin(θ) = mλ

Central maximum width: W = 2λD/a

Where: a = slit width, λ = wavelength, m = order, D = screen distance
