Photon ✔️A discrete unit or package of light energy
Photoelectric Effect ✔️The emission of electrons from a metal when electromagnetic radiation of high
enough frequency falls on the surface
Threshold Frequency (f₀) ✔️The minimum frequency of light needed to eject electrons from a metal
surface
Work Function (Φ) ✔️The minimum energy needed to eject electrons from the surface of a metal
Millikan's Stopping Potential Experiment ✔️An experiment utilizing reverse voltage raised to such a
level (stopping potential Vs) that it stops all emitted photoelectrons (NOTE: This experiment is used to
test the Einstein model of the explaining the photoelectric effect.)
de Broglie Hypothesis ✔️All particles can behave like waves whose wavelength is given by λ = h/p
where h is Planck's constant and p is the momentum of the particle.
Matter Waves ✔️All moving particles have a "matter wave" associated with them whose wavelength is
the de Broglie wavelength.
Wave-Particle Duality ✔️Both matter and radiation have a dual nature. They exhibit both particle and
wave properties.
Davisson-Germer Experiment ✔️An experiment showing that electrons are scattered off crystals of
nickel and interfere with each other - also know as "electron diffraction" (NOTE: This experiment is
evidence for the existence of matter waves.)
Electron in a Box Model ✔️A model of the atom useful for explaining the origin of atomic energy levels:
The model assumes that, if an electron is confined to move in one dimension by a box, the de Broglie
