LIGHT DWELLETH


"Where is the way where light dwelleth? and as for darkness, where is the place thereof, [Job 38:19]

Light originates as single photons, or particle/waves having zero mass, no electric charge, and an indefinite lifetime. Photons are emitted by electrons as they lose orbital energy around their atom. The expendable orbital energy is transferred to the electron either when it is bumped by an atom or when it is struck by another photon. Before being excited to a highter electron shell, the electron is in the lowest possible shell, or ground state.

light is nothing more than electromagnetic waves which can be sensed by our eyes. it came from lanterns! when you give energy to a material (a lamp filament for instance), i.e. heat it, electrons of its atoms get energy and travel to a higher level of energy(orbit). but in this state, atom is unstable so the raised electrons come back to their original orbit which has a lower level of energy. this energy difference(between two orbits) is emitted by an electromagnetic wave which sometimes is visible light.
