Physics - The photoelectric effect experiment
The photoelectric effect experiment
The photoelectric effect was a landmark discovery - it completely changed
our view of the nature of light.
Two metal plates are set up, and Light of a particular frequency shines
on plate and electrons may be ejected. Electrons that are ejected are
To measure the initial kinetic energy of the electrons, a potential
difference is created between the plates. When a current is registered, it
means that electrons are travelling the full distance between the plates.
