This document discusses different types of mirrors and how they form images. It describes plane mirrors, which produce images of the same size as the object, and curved mirrors, including concave mirrors that can produce real or virtual images depending on the object's position, and convex mirrors that only produce smaller virtual images. Ray diagrams are introduced as a way to determine the characteristics of images formed by mirrors and lenses. Specific examples of image formation using ray diagrams are provided for concave and convex mirrors.

2. MIRROR
A reflective surface that
bounces off light, thus
producing a real or virtual
image

3. PLANE MIRROR
▪ A flat mirror that sends light
out from itself in multiple
directions.
▪ The image formed by a plane
mirror will always be the same
size as the original object.

4. 12 inches 12 inches

7. PLANE MIRROR
▪ It is virtual
▪ It is erect and of the same
size as the object
▪ It is laterally inverted

8. CURVED or
SPHERICAL MIRRORS
▪ Concave Mirror
▪ Convex Mirror

9. CONCAVE MIRROR
▪ It bends light further away in the middle,
more like the inside of a bowl.
▪ How images appear depends on the
proximity of objects to the mirror.

10. CONVEX MIRROR
▪ It curves light away from its middle, like
the outside portion of a bowl.
▪ This type of mirror will produce only
smaller and virtual images.

12. RAY DIAGRAMS
Diagrams which are used to determine
the location, orientation, size, and type
of image formed in mirrors and lenses
