Interference of Light

  • Constructive interference
  • Destructive interference
  • Fringes

Constructive and destructive interferences produce fringes pattern in a spatial screen such as what happened in the double-slit interference pattern.

Interferometer:

An optical device which can be used to investigate light interference and fringe patterns.

Some popular interferometers:
  • Michelson stellar Interferometer
  • Mach Zehnder Interferometer
  • Twyman–Green Interferometer
  • Fizeau Interferometer
  • Jamin Interferometer
  • Moiré Interferometer
  • Fabry Perot Interferometer
