Light Wave: Reflection

All waves are known will undergo reflection or bounce of off an obstacle. For example sound wave, or water wave even light wave. Since light wave will only go straight line it will bounce if it approaches a flat reflecting surface. The reflection of light wave are usually bounce from a mirror when a light source is directed at it. Furthermore the direction of the bounced wave is influenced by the angle the source of the light is being directed at a flat reflecting surface plus the size or the density of the light waves is also influence the distance between the source and the bounce-able obstacle.
