Document Summary

Light is a wave & a particle, this is how they are related (c is the speed of light) c (m. s-1(cid:895) = (cid:894)(cid:373)(cid:895) (cid:454) (cid:894)s-1) Electromagnetic (em) radiation: visible spectrum 400-700, longer wave lengths are closer to ir, shorter wave lengths are closer to uv. It means that we have defined differences between energies of the system, this is called quantum of energy! Photoelectric effect: if the photon does not have enough energy then no electron is ejected.
