A) photodecomposition
B) phosphorescence
C) fluorescence
D) spectroscopy
E) luminescence

Question

Quizplus · Accepted Answer

Fluorescence is the rapid emission of light by an excited molecule. Photodecomposition refers to the breakdown or decomposition of a molecule under the influence of light. Phosphorescence is the emission of light by a substance after it has absorbed energy and then gives off light slowly over time. Spectroscopy is the study of the interaction between matter and electromagnetic radiation. Luminescence is a general term for the emission of light, including fluorescence and phosphorescence.
