You can see your reflection in any shiny surface, from a metal spoon to a puddle of water. Sometimes
the reflection is sharp and clear, like the reflection from a mirror. This is called regular
reflection. At other times the image is fuzzy, like the reflection in moving water. This
is called diffuse reflection. In a regular reflection, parallel light rays hit a smooth
surface and are all reflected at the same angle. While in a diffuse reflection the light
rays are reflected in different angles.
