áttetszéség

Áttetszéség, in Hungarian, refers to the physical property describing a material's or medium's ability to allow light to pass through. In optics, it is a key characteristic of transparent materials, such as glass, clear plastics, or certain crystals. The degree of transparency depends on factors like the material's composition, internal structure, and presence of impurities or defects. High transparency is crucial in applications including optical lenses, windows, and displays, where light transmission efficiency is essential. Conversely, low transparency (opacity) occurs in materials like wood or metals. Measurement of transparency typically involves assessing transmittance— the fraction of incident light that passes through the material. Understanding and controlling áttetszéség is vital in fields like materials science, optics, and engineering, enabling the development of functional transparent components for various technologies.
