If atoms can only emit certain photons , like hydrogen has only certain spectral lines in the visible spectrum , then how come when i shine pretty much any color of light through glass
it hits the atoms in the glass and then re-emits them , what are the spectral lines for glass
(silicon dioxide) , it certainly would not be a continuous spectrum , so why can white light go through glass and come out if it contains all colors of light .? Wouldn’t some of these colors be in-between the band gap , and I might get a different color out then what I shined into the glass , is this what dictates whether a material is transparent or not.
