optical transparency

Optical transparency refers to a material's ability to let light pass through with minimal scattering or absorption. When a substance is transparent, you can see clearly through it, like glass or clean water, because most of the light travels straight through. This property depends on the material’s molecular structure and how it interacts with light. Transparent materials are essential in applications like windows, lenses, and displays, where clear visibility is important. Factors such as impurities or surface quality can affect transparency, making the material appear cloudy or opaque.
