In the process of fluorescence, an atom ab-
sorbs a photon of ultraviolet light and emits
two or more photons of visible light.
Is the reverse process possible? (That is, is
it possible for an atom to absorb a photon of
visible light and emit photons of ultraviolet

1. Yes; ultraviolet photons have less energy
than visible light.
2. No; ultraviolet photons have more energy
than the visible light.
3. Yes; the energy is equal;
4. More information is needed.
5. None of these
