Calcium reacts with oxygen to form calcium oxide. The chemical equation for this reaction is Ca + O2 → CaO.
During absorption, frequency of the incoming light wave is either near or at the energy level of the electrons in the matter of the material. The electrons will absorb the energy of the light wave and change their energy state.
Hope that helps! :)
