Just as was hypothesized by Planck and by Einstein for the energy of the quanta of light. Once again, the key is a granularity, but now not for the energy of light but rather for the energy of the electrons in the atom.
This explains the dualaity of the positive and negative charges inherent in electromagnetic spectrum... More curious why the human form can only physically see .0035 percent of the entire spectrum. Probably why in the theory of general relativty, Einstein's equation assumed space to be a void - physically empty
