läpinäytämätön

Läpinäytämätön is a Finnish adjective that translates to opaque in English. It describes something that light cannot pass through, making it impossible to see what is on the other side. This property is the opposite of transparent or translucent.

The term can be applied to a wide variety of materials and objects. For example, a solid wall is läpinäytämätön, as is a piece of dark fabric or a painted surface. In contrast, glass is transparent, allowing light to pass through freely, while frosted glass is translucent, allowing light to pass but scattering it so that objects behind it are blurred.

In everyday language, läpinäytämätön is often used to describe containers that hide their contents, such as opaque bottles or bags. It can also be used metaphorically to describe something that is difficult to understand or interpret, lacking clarity or transparency in its meaning or intention. For instance, a decision that is made without explanation might be described as läpinäytämätön.

The concept of opacity is important in various fields, including physics, optics, and materials science, where the transmission of light is a key characteristic. Understanding whether a material is läpinäytämätön helps in determining its suitability for different applications, from windows and filters to artistic materials and protective coatings.
