A light guide is a device used to direct light from a light source (commonly an LED) to a place where the light is needed. Light guides are also sometimes referred to as light pipes.
Although light can travel through a vacuum, it can not travel through all objects. When light strikes an object, it can be transmitted, reflected or absorbed. The object is made of molecules, and each molecule has electrons, capable of jumping to higher energy levels by absorbing energy. A ...
light outside the wavelength range of the excitation beam and light of wavelength other than the laser is formed on a support layer that absorbs most of; was irradiated sufficient time to UV in an area it is desired b) is not a pixel within that layer of the excitation beam the absorptio...
being reflected. this can result in a larger portion of light being absorbed or transmitted through the surface rather than being diffusely reflected. as the angle of incidence increases, the scattering becomes more uniform in all directions. how is diffuse reflection used in fiber optic ...

A recent Harvard study examined thenegative impact of blue light on sleep patterns. Not all light is absorbed by the body, specifically our eyes, in the same manner. Green light, for example, has longer wavelengths and contains less energy than blue light. ...
light. A team of physicists at Bielefeld University, the University of Kaiserslautern, and the University of Würzburg have now proved that the very efficient scattering of light in ultrathin rough films traps light until it is absorbed completely. The researchers are now publishing their findings ...
Cherish every minute of learning, the use of a second short to absorb a small part of the knowledge, the knowledge accumulated absorbed every minute there will be a lot of knowledge. That time will become a part of your success, that part is priceless and valuable. Cherish a minute and ...

is a push towards us accepting the white light at death and going into it.Whether consciously or unconscioisly, there are those of influence who help to push this agenda and there are those who are doing their best to expose it. Many of the elxamples I give are from one who are...
