Diffraction Gratings

Cards (4)

  • A diffraction grating is a flat opaque screen with multiple evenly spaced parallel slits
  • Advantages of Diffraction Gratings
    1. Diffracted beams are further apart, so less uncertainty when measuring
    2. Beams are brighter and sharper
  • More slits means sharper and brighter beams
  • Decreasing frequency causes an increase in fringe separation
