Plane Mirrors Flat mirror that is most common. The image we see in a mirror is called a virtual image. [

Click here for virtual image demo Virtual image in a plane mirror is inverted.

When viewed in a rear-view mirror, “Ambulance” is correct! [

Concave Mirrors Surface of mirror curves inward. Light waves will reflect off of surface and combine at a focal point. [

Concave Mirrors Can create a virtual image if the object is within the focal length. Magnifies the object… [

Concave Mirror Ray Diagram Object Distance < Focal Length Virtual Image: Upright & Magnified Incoming Light Waves Reflected Light Waves

Concave Mirrors Can create a real image if the object is twice the focal length. [

Concave Mirror Ray Diagram Real Image: Upside down (Size can change!) Object Distance > Focal Length Incoming Light Waves Reflected Light Waves

Convex Mirrors Surface of mirror curves outward. Shrink images, but allow you to see more area.

Convex Mirrors “Objects in mirror are closer than they appear” Only create virtual images [
