1. Reflection

   • If light meets a rough surface, each ray obeys the law of reflection. However, the different parts of the rough surface point in different directions, so the light is not all reflected in one direction. Instead, the light is reflected in all directions.
     • This is called diffuse scattering. It explains why you can see a clear image of yourself in a shiny flat mirror, but not in a dull rough wall.
   • When light reaches a mirror, it reflects off the surface of the mirror.
     • The incident ray is the light going towards the mirror
     • The reflected ray is the light coming away from the mirror
