Who is Erwin Schrödinger?
This physicist formulated the wave equation of quantum mechanics.
What is n in quantum mechanics.
This principal quantum number determines the energy level of an electron.
What is quantum tunneling?
The phenomenon in which particles pass through barriers classically impossible to cross.
What is operator?
What is E=hf
The fundamental equation relating the energy of a photon to its frequency
What is the Schrödinger equation?
This equation describes the time evolution of a quantum system
What is the azimuthal quantum number (l)?
This quantum number determines the shape of an orbita
What is quantum entanglement?
Einstein called this phenomenon "spooky action at a distance
What is commutation?
Operators whose measurements can be simultaneously known exactly must satisfy this condition
What is superposition?
This property allows a quantum particle to exist in multiple states simultaneously
What are eigenvalues
Solutions of the Schrödinger equation correspond to these measurable quantities
What is ml in quantum mechanics?
The magnetic quantum number is represented by this symbol
What is electron diffraction?
This effect demonstrates the wave nature of electrons.
What is the Heisenberg Uncertainty Principle?
Position and momentum can not be determined simultaneously.
What is the wavefunction?
The mathematical function that describes a quantum state.
What is the Hamiltonian operator?
The operator representing the total energy of a system
What is ms in quantum mechanics?
This quantum number specifies the orientation of an electron spin
What is the Zeeman effect?
The splitting of spectral lines in a magnetic field is known as this effect.
What is the Spin-Statistics Theorem?
The theorem stating that identical fermions have antisymmetric wavefunctions.
What is probability density?
The square of the magnitude of the wavefunction gives this quantity.
What is time independent (constant in time)?
In quantum mechanics, a stationary state has a wavefunction whose probability density is this
What is the Pauli Exclusion Principle?
According to this principle, no two electrons in an atom can have the same set of four quantum numbers.
What is the double-slit experiment?
This experiment demonstrated that measuring which slit a particle passes through destroys the interference pattern.
What is the Copenhagen Interpretation?
The quantum mechanical interpretation stating that measurement causes wavefunction collapse
