Glossary
opacity
Opacity refers to the degree to which something is not transparent or translucent, meaning that it doesn't allow light to pass through it easily. It's a measure of how much a material obstructs the transmission of light. In a broader sense, it can also refer to the degree to which something is difficult to understand, obscure, or not easily seen through. This term is commonly used in various fields including physics, chemistry, art, and even metaphorically in language and communication.
