Objectives

 Mirrors
o Distinguish between Concave and Convex

mirrors.
o Describe a simple ray diagram.
o Distinguish between real and virtual images.
Mirrors Outline

 Types of Mirrors
o Convex

o Concave
o Spherical
o Parabolic

o Examples
Mirrors

 Concave
o How light reflects
o Examples

 Simple Ray Diagram
o Explanation and Examples
 Real vs. Virtual Images
o Real Images

o Virtual Images

 Demonstrations
 Evaluation Questions
We are going to explore how concave
and convex mirrors work along with
describing the simple ray diagrams that
go along with each one. We will also
discuss the real and/or virtual images
that both of these mirrors produce.
Different Types of Mirrors
Convex
Concave

Spherical
Parabolic
Straight or Plane mirror
Mirrors ppt
Concave
Concave

 Reflection
 Curved inward reflective surface
 Used to magnify
 Produces Real and Virtual Images
o depend on objects distance from the

surface of the mirror and the focal length.
Mirrors ppt
Convex
Convex

 Reflection
 Image is small or reduced in size
 Image is upright
 Image is located behind the convex
mirror

 Image is always virtual
Mirrors ppt
Convex- smaller image
Concave- magnified image
Mirrors ppt
Simple Ray Diagram

 Tool used to determine
o location
o size
o orientation

o type of image formed
Real or Virtual
 Straight/

Plane mirror

 Extended

Reflected
Rays make
up image

 Behind the
mirror
Simple Ray Diagram for Concave
Mirrors

Whether the image is upside-down or rightside up
depends of the distance you are from the mirror
and the focal length of each mirror.
Simple Ray Diagram for Convex
Mirrors

Real vs. Virtual Images



Virtual image
o Object is less than the focal length of the mirror
o Can only be seen by looking at the mirror, not
projected
Real Image
o object is further than focal length of mirror
o Can be projected and everyone in the room can look
at it
