The fact of the matter is that the standrd mirror that we have in our homes DO ABSORB LIGHT
"
Mirrors come in two basic varieties. The most common are metallic mirrors like those found on the walls of Versailles or on medicine cabinets. Metallic mirrors work pretty well, but they have limitations. The most important is that they waste energy, absorbing a small fraction of the light that falls on them. That is because when light, which, like radio waves, is a form of electromagnetic radiation, strikes a metallic mirror the electrons in the metal move just as they do when a radio signal strikes an antenna. Pushing electrons around takes energy, which dims the reflected image. So metallic mirrors cannot be used in applications like communications and high-powered lasers, where minimizing energy loss is important.
For applications in which energy loss is important scientists depend on a more sophisticated device known as a dielectric mirror. A dielectric is a material like glass or plastic, that does not conduct electricity. Narcissus was actually enamored of his image in a crude sort of dielectric mirror, because water is a dielectric. But dielectrics like water or glass do not reflect light well, so practical dielectric mirrors are made by stacking alternating thin layers of two dielectrics. Every time light passes from one layer to the next a little bit of it is reflected. If the thicknesses of the layers are chosen carefully these reflected light waves combine and reinforce one another, strengthening the intensity of the reflected light. By stacking many layers scientists can make mirrors that are nearly perfect reflectors"
However if you have lots of maney to spend then you would be able to get a mirror that doesnt absorb light.
That's a good thing though.............lolololo
