Michelson interferometer

Principle

In the Michelson arrangement interference will occur by the use of 2 mirrors. The wavelength is determined by displacing one mirror using the micrometer screw.

Benefits

• Discover the essence of the Physics Nobel Prize of 1907
• Lead to experimental findings that only special relativity theory could explain
• Pre-setup of the critical components makes for short preparation time
• Digital data aquisition
