photochemistry

/fˌoʊɾoʊkˈɛmɪstɹi/ noun

The study of photochemical reactions.

Word Origin A blend of Greek phōs 'light' and Arabic al-kīmiyā 'alchemy' — the ancient art of transformation. So photochemistry is literally the alchemy of light, studying how light triggers chemical reactions. The photo- part connects to photograph, photon, photosynthesis, while chemistry traces back to alchemy, the medieval quest to transmute matter. A great example of how modern science still carries echoes of old magic.
