Hi,
I can explain why objects reflect, absorb or transmit light by referring to the objects' refractive index (differnece of the refractive index of two media).
I'd like to know if there is a microscopic point of vue that can explain why objects reflect light?
For example
* Light is transmitted if the band gap of molecules (LUMO - HOMO) in the object is larger than the energy of the incident light (hv)
* Light is absorbed if the energy of the incident light (hv) correspond to specific energy levels of the electrons in the molecule.
* And what is the condition for light to be reflected? And can anyone recommend me some books or websites that I could read to get more informations about this?
