Fotochémiques
Fotochémiques is a term that refers to photochemical reactions, which are chemical reactions initiated by the absorption of light. The word itself is a portmanteau of "foto" (Greek for light) and "chimique" (French for chemical). These reactions are fundamental to many natural and artificial processes.
In nature, photosynthesis is a prime example of a fotochémique process. Plants use sunlight to convert carbon
Artificial applications of fotochémiques are widespread. Photography, in its traditional film-based form, relies on light-sensitive silver
