Young's Double-slit experiment is a simple demonstration of the wave nature of light. It experimentally verifies that just like waves interfere, light also interferes and forms interference fringes. The setup of Young's double-slit experiment consists of two coherent sources(in form of slits) separated by a small distance 'd'. A screen is placed at a distance 'D' from the point slits to observe fringes. The path difference between the light rays from the two slits introduces a phase difference. This phase difference leads to the formation of interference fringes.

                              Additional Information

  • In YDSE, all the bright fringes are of equal intensity and all the dark fringes are of the same intensity.
  • The shape of the fringes obtained is Hyperbolic.
