Interference experiment

Article no. P2220103 | Type: Experiments

University

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

  1. with Fresnel mirror,
  2. with Fresnel biprism.

Learning objectives

  • Wavelength
  • Phase
  • Fresnel biprism
  • Fresnel mirror
  • Virtual light source
