Ch.2 Flashcards
The wavelength of a particle given as the ratio of Planck’s constant to momentum
De Broglie wavelength
The principle that states that we cannot describe with absolute accuracy the relationship between sets of conjugate variables that describe the behavior of particles, such as momentum and position
Heisenberg uncertainty principle
The principle that states that no two electrons can occupy the same quantum state
Pauli exclusion principle
The particle-like packet of electromagnetic energy
Photon
The particle-like packet of thermal radiation
Quanta
The allowed discrete energy levels that bound particles may occupy
Quantized energies
A set of numbers that describes the quantum state of a particle, such as an electron in an atom
Quantum numbers
A particular state of an electron that may be described, for example, by a set of quantum numbers
Quantum state
The quantum mechanical phenomenon by which a particle may penetrate through a thin potential barrier
Tunneling
The characteristic by which electromagnetic waves sometimes exhibit particle-like behavior and particles sometimes exhibit wave-like behavior
Wave-particle duality
