Description

Animation of the wave pattern at the central five maxima of a two slit experiment. The wavelength is 800nm, and the slit separation is 0.1mm and the screen is 5m away. 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
  • L is the distance to the screen
