Diffraction of Light by a Single Slit

( \newcommand{\kernel}{\mathrm{null}\,}\)

This browser doesn't support HTML5 canvas!
Wavelength:nm
Width of slit:nm
Angle:°
Minima:
Maxima:
Relative intensity:1.0000
W. Fendt 2003
Condition for a maximum (approximation):
α = 0°   or   b sin α  ≈  (k + ½) λ

b ... width of slit
α ... angle
k ... order of the maximum (1, 2, 3, ...)
λ ... wavelength

Condition for a minimum:
b sin α  =  k λ

b ... width of slit
α ... angle
k ... order of the minimum (1, 2, 3, ...)
λ ... wavelength
