Conservation of energy example #1) photon creation – atoms when an electron is captured into an atom, or moves to a lower orbital energy level, a photon is released. This is a transverse wave as a result of particle vibration as it settles into place. Each particle (proton and electron) has longitudinal, standing wave+ read more.
