The 24 pages that link to Energy level, each with the reason it gives.

• SpectroscopyRelated: Spectral frequencies commonly encode differences between energy levels.

• Absorption spectrumRelated: Differences between energy levels determine which photon energies can be absorbed.

• PhotoluminescenceRelated: Differences between material energy levels set the energies of absorbed and emitted photons.

• Stimulated emissionRelated: The energy gap between levels fixes the emitted photon’s frequency.

• Absorption spectroscopyRelated: Spectral absorption reflects transitions between distinct energy levels.

• Emission spectrumRelated: Differences between energy levels set the energies of emitted photons.

• Canonical ensembleRelated: The energy of each state controls its Boltzmann weight.

• Excited stateRelated: An excited state occupies an energy level above the ground level.

• Absorption (electromagnetic radiation)Related: A photon can be absorbed when its energy matches an allowed transition between levels.

• Spontaneous emissionRelated: The energy difference between levels fixes the emitted photon's frequency.

• Laser spectroscopyRelated: Spectral frequencies correspond to energy differences between allowed states.

• Quantum statisticsRelated: Equilibrium distributions assign populations to states according to their energies.

• Atomic physicsRelated: Atomic energy levels determine which transitions and photon energies are possible.

• Optical spectroscopyRelated: Spectral features arise when matter changes between energy levels.

• Bose–Einstein distributionRelated: Each state's energy enters the distribution's exponential factor.

• Bose gasRelated: The gas’s occupation numbers are distributed across its available energy levels.

• Impurity (semiconductors)Related: Impurities introduce energy levels inside the semiconductor band gap.

• Potential wellRelated: Quantum wells support particular allowed energies rather than a continuous range.

• QuantumRelated: Discrete energy levels make the idea of distinct energy amounts measurable in bound systems.
