PROBLEM TO BE SOLVED: To provide glass which absorbs ultraviolet light, passes yellow light in a visible light range, and can be used not only for the containers of tungsten.halogen lamps and other high temperature light sources but also for the containers of shield beam incandescent lamps....
"The problem with soot is that it absorbs ultraviolet light, and that means that it could heat the stratosphere," Rosenlof said. "When you start heating the stratosphere, the layer above the troposphere [closest to the ground], you start changing the motion in the stratosphere. You are chan...

of light and re-emits a color with a longer wavelength. in the case of a fluorescent bulb, there is a coating on the inside of the glass that absorbs ultraviolet light (which you can’t normally see) and re-emits it as visible light. yes, it’s a complicated process, but that’s ...
scintillation - (physics) a flash of light that is produced in a phosphor when it absorbs a photon or ionizing particle streamer - light that streams; "streamers of flames" torchlight - light from a torch or torches twilight - the diffused light from the sky when the sun is below the hor...
Energy levels that excite electronic transitions are studied in ultraviolet-visible (UV-vis) spectroscopy. UV-vis light absorbs and excites molecules in their ground states to their excited states. Vitamin research in the 1930’s revealed that a number of vitamins, especially vitamin A, absorb ...
1. Photosynthesis: Light is essential for photosynthesis, the process by which plants convert light energy into chemical energy. Chlorophyll, the pigment responsible for capturing light, absorbs different wavelengths of light, primarily in the red and blue regions of the spectrum. This enables plants...

Ozone.This gas found in the upper atmosphere absorbs UVradiation. The more ozone, the fewer sun rays reach the ground. Ozone found on ground level is the main ingredient in smog and can harm your health. Ozone levels vary each day and throughout the year. ...
