Why is glass transparent?
PS MESSAGE FROM PROF MORIARTY: "I misspoke for the last sentence of the video. What I meant to say is that the photons don't have enough energy to excite electrons across the energy gap and therefore light is transmitted. What I said was precisely the opposite, contradicting everything else in the video. Apologies for any confusion caused.”
If the glove don’t fit, you can’t convict… oops, er I meant to say, if the photon wavelength does not match a band gap in the atom or molecule, it must pass through.
