a chemical reaction that involves or requires light
Word origin
[1905–10; photo- + reaction]This word is first recorded in the period 1905–10. Other words that entered Englishat around the same time include: cadre, jazz, persona, thiamine, white listphoto- is a combining form meaning “light” (photobiology); also used to represent “photographic” or “photograph” in the formation of compoundwords. Other words that use the affix photo- include: photocoagulation, photogenic, photogravure, photopathy, photorealism
