By dividing up the wave-front of a beam of light at the Fresnel mirror and the Fresnel biprism, interference is produced. The wavelength is determined from the interference patterns.


  • observe that light plus light can result in darkness
  • understand how to make use of the interference effect
  • a laser as lightsource allows clear observation
