IB Physics Double Slit Interference

A tutorial sheet on Young’s double slit experiment follows.

  1. A Young's double slit experiment is carried out with the wavelength much greater than the slit separation. Describe the intensity pattern on a distant screen.
  2. In a Young's double slit experiment the wavelength is much less thn the slit separation. Describe the intensity pattern on a distant screen.
  3. In a double slit experiment with slits of width b separated by a distance d are all of the maxima on a distant screen of the same intensity?
  4. A double slit experiment is carried out with b much less than d. Describe the intensity variation on a distant screen.
