Photochemistry, Photobiology and Electrochemistry

Photochemistry is the category of chemistry treated with the chemical effects of light. Commonly, this phase is used to describe a chemical reaction influenced by the absorption of ultraviolet (wavelength from 100 to 400 nm), visible light (400–750 nm), or infrared radiation (750–2500 nm).

Photobiology is mainly defined to cover all biological aspects including non-ionizing radiation. It is noticed that photo biological responses are the result of chemical and/or physical variations induced in biological systems by non-ionizing radiation.

Electrochemistry is the knowledge of electricity and how it compares to chemical reactions. In electrochemistry, electricity can be produced by actions of electrons from one element to another in a reaction is called redox or oxidation-reduction reaction and it is the part of chemistry involved with the interrelation of electrical and chemical variations that are produced by the passage of current.
