Have you looked at the wikipedia page for soda lime glass? It shows a typical transmission spectrum for said glass.Danyon said:How much or what percentage of visible light is absorbed by glass, and how much glass would it take to completely stop a laser beam in the visible spectrum?
A lot. Such a vague question can only have a vague answer.Danyon said:how much glass would it take to completely stop a laser beam in the visible spectrum?
Glass is composed of a network of atoms with varying electron configurations. When light passes through glass, the electric field of the light wave interacts with the electrons in the glass. The electrons absorb the energy from the light wave, which causes them to vibrate and re-emit the light in a different direction.
The arrangement of atoms in glass allows certain wavelengths of light to pass through with minimal interaction, while other wavelengths are more easily absorbed. This is due to the specific electron configurations of the atoms in glass, which determine the amount of energy that can be absorbed from light waves.
The thicker the glass, the more distance the light must travel through the material. This means that more interactions between the light and the glass occur, resulting in a greater amount of light being absorbed. Thinner glass allows more light to pass through without being absorbed.
Yes, the amount of light absorbed by glass can be controlled by altering the composition of the glass or by adding coatings. For example, tinted or coated glass can selectively absorb certain wavelengths of light, allowing only specific colors to pass through.
The absorbed light is converted into thermal energy, causing the glass to heat up slightly. This is why objects placed behind glass, such as plants in a greenhouse, can absorb more heat from the sun than objects outside of the glass. Eventually, the thermal energy is dissipated through conduction and convection, causing the glass to cool back down.
