What is the transmission of light through glass called?
transparency 1) “In optics, transparency is the material property of allowing light to pass through. In mineralogy, another term for this property is diaphaneity. The opposite property is opacity. Transparent materials are clear: they can be seen through. Translucent materials allow light to pass through them only diffusely: they cannot be seen through.” “Though transparency usually refers to visible light in common usage, it may correctly be used to refer to any type of radiation. For example, flesh is transparent to X-rays, while bone is not, making X-ray imaging useful for medicine. Examples of transparent materials are air and some other gases, liquid such as water, most glasses, and plastics such as Perspex and Pyrex. Where the degree of transparency varies according to the wavelength of the light, the image seen through the material is tinted. This may be due to certain metallic oxide molecules in glass, or larger colored particles, as in a thin smoke. If many such particles are
