WebAug 1, 2012 · That is not true for highly reflective substances like metals. As most of the light is reflected, hardly any energy is absorbed. In the case of gold, the yellow colour is due to reduced reflection in regions where there are absorption lines due to transitions from d-orbitals to the conduction band. In the infrared the absorbance α is very small. WebThe properties which determine whether the metal surface is mirror bright are precisely determined by STM investigations. Mirror brightness of metal surfaces can be associated with the high degree of mirror reflection which approaches very nearly the ideal reflectance of the same metal.
