An excited atom decays to its ground state and emits a photon of green light. If instead the decay is to an intermediate state, then the light emitted could be
A)red.
B)violet.
C)blue.
D)any of the above
E)none of the above

Question

Quizplus · Accepted Answer

When an atom decays to an intermediate state, the energy of the emitted photon is less than that of the photon emitted when decaying directly to the ground state. Since green light is of higher energy than red light, the emitted photon could be red.
