A Photochemist investigates the chemical effects of light.  Photochemistry is a chemical reaction caused by absorption of ultraviolet, visible light or infrared radiation or a reaction that produces light. Photochemists may be interested in spectroscopy- splitting up light into it’s different colours to find out about the properties of the object being studied. They may be interested in photosynthesis, the way a plant generates energy from light. They may also study animals who use bioluminescence to signal to other animals or to lure prey.
