Photochemistry - Wikipedia

Photochemistry is the branch of chemistry concerned with the chemical effects of light. Generally, this term is used to describe a chemical reaction caused by absorption of ultraviolet (wavelength from 100 to 400 nm), visible light (400–750 nm) or infrared radiation (750–2500 nm).. In nature, photochemistry is of immense importance as it is the basis of photosynthesis, vision, and the .
