Should be easy - if you were paying attention

  • 1
    Which of these is not a condition for destructive interference?
  • 2
    What does coherent mean?
  • 3
    What is the central maximum?
  • 4
    If the two slits are 10mm apart and they produce an interference pattern on a screen 30cm away where the distance between the central maximum and the first subsidiary maximum us 25mm, what was the wavelength of the wave?
  • 5
    fringe width = 1.0cm
    wavelength = 0.1cm
    spacing between sources = 2.0cm
    What is the distance to the screen?
  • 6
    What is the main feature of Huygen's theory?
  • 7
    Why is the double slit experiment important?
  • 8
    What is the path difference for constructive superposition?
  • 9
    What do you get if a wave reflects back on itself?
  • 10
    What is a node?
