Types of mirror When we draw a ray diagram we represent a mirror by drawing a line with dashes on the silvered (non-shiny) side. Most mirrors are flat.
Light wave Recall: Light must reflect off of an object before it can be used to see the object. A flat mirror is called a plane mirror. A plane mirror.
Mirror – a shiny object that reflects light instead of letting the light go through.
