the way i understand it is photons excite atoms, causing them to increase in energy. i view this increase in energy as jostling of a atom causing more movement of its proton, neutrons, electrons. i realize a photon is a particle and a wave(in limited comprehension.) so should i view the transfer for energy as a vibration(wave form of light) traveling then hits a medium(atom), causing a vibration as it passes through? or should i view this as a particle passing through passing through a systems(atoms) orbit. much like a rogue planet passing through a solar system effects caused by gravity possible collision? or neither?
