Photochemistry
Photochemistry (pronounced: /ˌfoʊtoʊˈkɛmɪstri/) is the branch of chemistry concerned with the chemical effects of light. Generally, this term is used to denote the events involving absorption of photons by atoms or molecules and the subsequent physical or chemical effects of the absorbed radiant energy.
Etymology
The term "Photochemistry" was first used in the early 19th century and is derived from the Greek words "phos" (meaning light) and "chemistry," which refers to the study of matter and its properties.
