Chemistry U2 Einstein / Photoelectric Effect

Albert Einstein
German physicist who developed the theory of relativity, which states that time, space, and mass are relative to each other and not fixed.

incident light
The light emitted from a source that strikes an object

kinetic energy
Energy of motion

photoelectric effect
The emission of electrons from a metal caused by light striking the metal

photoelectric emission
-the emission of an electron from the surface of a substance

photoelectron
ejected electron with energy equal to the energy of the incident photon

photon
a tiny particle or packet of light energy

threshold frequency
the minimum frequency of light required to produce the photoelectric effect

work function
The minimum energy required by a single electron to escape the metal surface

work
Force x Distance
