PHOTOREACTION Meaning and
Definition
-
A photoreaction, also known as a photochemical reaction, is a chemical reaction that is triggered by the absorption of light energy. It occurs when a substance, referred to as a photosensitive or photoactive compound, undergoes a transformation upon exposure to light. Photoreactions are widely studied in various fields of science, including chemistry, physics, biology, and materials science.
In a photoreaction, the absorbed light energy excites the electrons within the photosensitive compound, causing changes in the electronic structure and overall molecular configuration. This excitation can lead to various types of chemical processes, such as bond breaking or formation, rearrangement of molecules, or the activation of previously dormant chemical reactions.
Photoreactions play a crucial role in numerous natural and artificial processes, including photosynthesis, vision, photodegradation of pollutants, and the functioning of solar cells. They are also extensively utilized in chemical synthesis and the development of new materials with specific optical properties.
The study of photoreactions involves investigating the factors that affect their efficiency, such as the type and wavelength of light, the concentration and composition of the photosensitive compound, and the presence of any catalysts or reactants. By understanding the underlying mechanisms of photoreactions, scientists can develop strategies to control or optimize their outcomes, ultimately leading to important advancements in various scientific and technological applications.

Etymology of PHOTOREACTION
The etymology of the word "photoreaction" can be broken down as follows:
1. Photo-: This prefix is derived from the Greek word "phōs" (φῶς), meaning "light". It is commonly used in scientific terms related to light, such as photography, photovoltaic, etc.
2. Reaction: This word is derived from the Latin word "reactio" which means "a response to something", or "an action performed in return". It refers to a process or change resulting from the interaction of substances or components.
Combining these two components, "photoreaction" refers to a reaction or process that occurs in response to or is triggered by light.
