What term describes a material that allows light to pass through with some diffusion?

The term that describes a material allowing light to pass through with some diffusion is "translucent." Translucent materials permit the passage of light, but they scatter it, preventing clear images from being seen through them. This means that while light is still able to come through, objects on the other side are not clearly visible. Common examples of translucent materials include frosted glass and certain types of plastic.

In contrast, an opaque material does not allow any light to pass through, making it impossible to see through. Transparent materials, on the other hand, allow light to pass through with minimal diffusion, enabling clear visibility. The concept of reflection pertains to the bouncing back of light from a surface, not to the transmission of light through a material. Thus, the correct understanding of translucence highlights its unique ability to blend transparency and opacity.
