Technical data

Interference experiment

Article no: P2220103

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

Determination of the wavelength of light by interference

with Fresnel mirror,
with Fresnel biprism.
