läpikuultamatonta

Läpikuultamatonta is a Finnish adjective that translates to "opaque" in English. It describes a material or substance that does not allow light to pass through it. Unlike translucent materials, which allow some light to diffuse through, or transparent materials, which allow light to pass through clearly, opaque substances block light entirely.

This property is crucial in various applications. For instance, in art and design, opaque paints and pigments are used to create solid colors and cover underlying layers. In architecture and construction, opaque materials like concrete, brick, and wood are used for walls and structural elements to provide privacy, insulation, and protection from the elements. In optics, opaque screens or barriers are used to control the direction of light or create shadows. The degree of opacity can vary greatly, from slightly see-through to completely impenetrable to light. Understanding the opaqueness of a material is fundamental when selecting it for a specific purpose, as it directly impacts its visual appearance, functional capabilities, and interaction with light.
