Michelson and Fabry-Pérot Interferometer

• Study electron photoemission from a metal surface
• Obtain the characteristic curves of a vacuum photocell
• Explore the effect of illumination intensity using the inverse square law

The Photoelectric Effect Apparatus allows the photoelectric emission from a mixed metal cathode in vacuum to be studied. It consists of a lighttight box connected to a control and measurement unit by shielded cables.
