Definition
Meaning and Definition
Electromagnetic radiation emitted by an atom, molecule, or nucleus when it transitions from an excited state to a lower energy state at a specific resonant frequency; often associated with the re-emission of absorbed radiation at the same wavelength.
More broadly, any radiation that results from a resonant interaction within a physical system, such as in plasma physics or quantum optics, where energy is absorbed and re-emitted at a characteristic resonant frequency of the system.

Common Mistakes When Using “resonance radiation”
- Using 'resonance radiation' to refer to any radiation that causes resonance. It is the radiation *resulting from* resonance.
- Confusing it with 'stimulated emission', which is a different quantum process.
- Using it in non-scientific contexts.
FAQ
Frequently Asked Questions
Not inherently. The term describes a physical process. The danger depends on the wavelength and intensity (e.g., UV resonance radiation can be harmful, while visible light resonance radiation is generally safe).
Resonance radiation is a specific type of fluorescence where the emitted photon has exactly the same energy (wavelength) as the absorbed photon. General fluorescence can involve Stokes or anti-Stokes shifts where the emitted light has a different wavelength.
Yes, while most commonly discussed for atoms, molecules also have resonant energy levels and can emit resonance radiation, particularly in the context of rotational-vibrational spectroscopy.
'Resonance radiation trapping' or 'imprisonment' refers to the phenomenon where re-emitted resonance photons are repeatedly absorbed and re-emitted by other atoms in a dense medium, effectively trapping the energy and delaying its escape. This is crucial in understanding the radiation transport in gases and plasmas.
Electromagnetic radiation emitted by an atom, molecule, or nucleus when it transitions from an excited state to a lower energy state at a specific resonant frequency.
Resonance radiation is usually technical/scientific in register.
Resonance radiation: in British English it is pronounced /ˈrɛzənəns ˌreɪdɪˈeɪʃ(ə)n/, and in American English it is pronounced /ˈrɛzənəns ˌreɪdiˈeɪʃ(ə)n/. Tap the audio buttons above to hear it.
