According to metal bond theory or electron sea model when light falls on a metal surface the electrons absorb them and oscillate and re-emit radiations which accounts for lustre. But how are properties of reflection satisfied on the surface of the metal. The electron could have emitted the radiation in any direction. but it isn’t so. Why is the direction of re-emission following the laws of reflection. To be specific What do we know about this direction of re-emission of radiation from a particle.
