poolläbipaistuse

Poolläbipaistuse refers to a state of matter or the property of a material that allows light to pass through it, but not in a perfectly clear manner. Unlike transparent materials, which allow light to pass through without significant scattering, or opaque materials, which block light entirely, translucent substances diffuse light. This means that while light can penetrate the material, its path is altered and scattered, making objects viewed through it appear blurred or indistinct.

Examples of translucent materials include frosted glass, parchment paper, and certain types of plastic. The degree of translucency can vary greatly. Some materials might be only slightly translucent, allowing a faint outline of objects to be seen, while others might be quite translucent, allowing for a more detailed, albeit still blurry, view. This property is often desirable in applications where diffused lighting is needed, such as in lampshades or privacy screens, to soften harsh light and reduce glare. The phenomenon of translucency is explained by the interaction of light waves with the internal structure of the material, where scattering occurs at the interfaces between different optical densities within the substance.
