Quantum physics

Use photons, matter waves and discrete atomic energies to explain observations that classical wave physics cannot.

TOPIC 22

Quantum physics

Use photons, wave–particle duality and quantised atomic energies to explain microscopic observations. Each diagram connects a quantum equation to the experimental evidence it explains.
