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.

Advanced Reflections

All light will reflect off a mirror at the same angle it enters in relation to the normal Even curved mirrors

Convex Mirror A convex mirror is a mirror that is curved out towards you The back of a spoon is a convex mirror

Incident Ray Normal

Incident Ray Normal Reflected Ray

Concave Mirror A concave mirror is a mirror that is curved in away from you The inside of a spoon is a concave mirror

Incident Ray Normal

Incident Ray Normal Reflected Ray

Parabolic Mirrors A special type of concave mirror is a parabolic mirror As the last diagram showed, all light rays coming into the mirror are reflected to one location This focuses all the light at one point Starting with a light source at the focus point, all reflected rays would be parallel This is used in flashlights like a MagLite

Additional Uses A satellite dish works like the concave mirror, only it is reflecting all the microwave signals from a satellite to the receiver in the arm of the dish Car Lights, Microscopes, Dentistry

Seeing a Mirror Image MIRRORMIRROR

Light coming from the object (incident) reflect off the mirror and come to your eye At the back of your eye, the retina converts these light waves into a signal processed by the brain and seen as an image The brain thinks the image is actually behind the mirror, and smaller than the actual image

Reflection; Image Formation by a Plane Mirror What you see when you look into a plane (flat) mirror is an image, which appears to be behind the mirror.
