Description
English: Density plot of two slit interference of 800nm light thtrough slits 0.1mm apart. The equation is:

where

  • d is the slit separations
  • k is the wavenumber = 2π/λ
  • x is the distance from the origin on the line containing the slits
  • y is the distance from the plane contining the slits
