Many materials have a well-characterized refractive index, but these indexes often depend strongly upon the frequency of light, causing optical dispersion. Standard refractive index measurements are taken at the yellow doublet sodium D line, with a wavelength () of 589 nanometers. There are also weaker dependencies on temperature, pressure/stress, etc., as

〉202197ヂ Metallic Reflection. When a light beam encounters a material, radiation can be absorbed or reflected by the surface. Metals are known for having high reflectivity, which explains their shiny appearance. Since the reflectance of light by metals is high their absorption is low because the sum of both must correspond to 100% of the incident light.
〉As the light rays enter into the more dense lens material, they refract towards the normal; and as they exit into the less dense air, they refract away from the normal. These specific rays will exit the lens traveling parallel to the principal axis.

〉The first is reflection. This is when all incoming rays of light are bounced back the way they came in. An example of this is a mirror, or a sheet of aluminum foil. Refraction is when the paths of the light rays get bent.
〉First, theres no perfect reflector nor absorber. In fact - even Aluminium does absorb some radiation (by which it gets heated, can be noticed at incident high frequency radiation). One more thing is that aluminium foils are designed in a way to reflect light.. Heres the Wiki article quote.... Aluminium foil has a shiny side and a matte side.
