An atom has the following energy of vibration: E= nhv. n can only be in the range of whole numbers. So if an vibrating atom changed energy, say from 6hv to 2hv, it means that 4hv of energy is released in light/photons Does that mean that 4 photons are "released" by the atom (?), because The energy of one photon is equal to hv ? Thanks for the help!!
