Absorption of light by solids: How is the energy (in electron-volts) carried by light with a wavelength, of say 514 nm, exchanged with the solid? What will be created in the solid by the absorption? What effect would the existence of an energy gap have?
This question is related to an experiment I have to do related to Bandgaps, but I don't seem to know the answer to it?
I know that electrons in the atoms of the solid get excited and thus the energy is transformed into heat, but this doesn't mention any band gaps in the solid.
