läpinäkymättömiä

Läpinäkymättömiä is a Finnish adjective meaning "opaque." It describes a material or substance that light cannot pass through. This is in contrast to transparent materials, which allow light to pass through them so that objects on the other side can be seen clearly, and translucent materials, which allow light to pass through but scatter it, making objects on the other side appear blurred.

In everyday language, läpinäkymätön can refer to a wide range of objects. For example, a solid wall is läpinäkymätön, as is a piece of dark fabric or a painted surface. In scientific contexts, the term is used in physics and optics to describe the optical properties of materials. Different materials have varying degrees of opacity, which can be measured. For instance, some materials may be nearly opaque, allowing only a tiny fraction of light to pass through, while others are completely opaque.

The concept of opacity is important in various fields. In art and design, opacity can be used to control visual effects and create depth. In engineering and construction, materials are chosen for their opacity based on requirements for privacy, light control, or protection from radiation. In photography and film, controlling opacity, often through filters or editing, is crucial for achieving desired image qualities. The Finnish word directly translates to "non-see-through" or "not transparent," clearly conveying its meaning.
