Definition

Noun: A material that allows light to pass through it diffusely, meaning it transmits light but scatters it so that objects on the other side are not seen clearly. It is a partly transparent material, distinct from being perfectly clear or opaque.

Usage

This term is used to describe a physical substance based on its optical property of diffuse transmission. It is a formal or technical term often found in scientific, industrial, or descriptive contexts. * The bathroom window was made of a transparent substance that provided privacy while still letting in light. * The chemist analyzed the transparent substance to determine its composition and light-diffusing properties.
