Interference experiment

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.

Description

Principle

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.

Benefits

  • 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
  • Digital data aquisition

Tasks
