PHOTOREACTIVE Meaning and
Definition
-
Photoreactive is an adjective that describes a substance or a process that undergoes a chemical or physical change when exposed to light. Derived from the words "photo," meaning light, and "reactive," meaning responsive, this term specifically denotes the property of a material or a system to react in some way under the influence of light.
Photoreactive substances can include various compounds, such as certain chemicals, polymers, or biological molecules, that exhibit a change in their intrinsic properties upon exposure to light. This change could involve alterations in color, shape, chemical structure, or physical properties such as solubility or reactivity. The chemical or physical reaction can be triggered by specific wavelengths or intensities of light, depending on the photoreactive properties of the substance.
Photoreactive processes are crucial in several scientific and technological applications. For instance, in photography, photoreactive silver halides on a film undergo a chemical reaction with light, resulting in the formation of an image. In the field of optoelectronics, photoreactive materials such as photovoltaic materials or photosensitive resists used in semiconductor manufacturing enable the conversion of light energy into electrical signals or the patterning of integrated circuits.
Overall, the term "photoreactive" refers to the capacity of a substance or a system to undergo a transformation when exposed to light, making it an essential concept in a wide range of scientific disciplines, from chemistry and materials science to biology and optoelectronics.

Etymology of PHOTOREACTIVE
The word "photoreactive" is derived from two roots: "photo-" and "reactive".
1. "Photo-" comes from the Greek word "phos" (φῶς), meaning "light". This root is commonly used in English words related to light, such as "photography", "photovoltaic", and "photocopy".
2. "Reactive" is derived from the Latin word "re-' (meaning "again" or "back") and "agere" (meaning "to act"). In English, the prefix "re-" indicates repetition or backward motion. When combined with "active", it implies a response or action in return.
Therefore, "photoreactive" combines "photo-" (meaning "light") with "reactive" (meaning "action in response"), resulting in a term that describes a substance or material that undergoes a chemical or physical change when exposed to light.
