This document discusses different types of curved mirrors and their properties. It distinguishes between concave and convex mirrors. Concave mirrors can produce real or virtual images, with real images being inverted and virtual images being upright. Convex mirrors only produce virtual, upright images. The document also defines real images, which occur when light converges, and virtual images, which appear to converge but do not. Finally, it describes ray diagrams and how they can be used to differentiate between concave and convex mirrors based on how incident rays interact with the focal point upon reflection.

2. Objectives
•
•
•
Distinguish between different types of
mirrors.
Describe a simple ray diagram.
Distinguish between real and virtual images.

3. Introduction slide
In this powerpoint we will be explaining
different types of mirrors, and attempting to
teach you how to distinguish between those
types. We will also explain the differences
between real and virtual images and also
describe ray diagrams.

4. Distinguishment of Curved
Mirrors
There are two types of curved mirrors which
both have an effect on the way we perceive
the images being reflected.

5. Concave Mirrors
•
Concave mirrors- They reflect the image; this
image may be real or virtual. Real images are
inverted and virtual images are upright.
Concave images are used to magnify.

6. Convex Mirrors
Convex mirrors- They reflect the image in a
way that causes us to perceive the image as
being smaller and upright. The image
reflected is a virtual image.

7. Real images
Real images are images where the light
actually converges. Real images are produced
when objects are placed outside the focal
length of a converging mirror.

8. Virtual images
Virtual images are locations where light just
appears to have converged. Virtual images
are formed by diverging lens or by placing an
object inside the focal length of a converging
lens.

9. Ray Diagrams
•
A Ray Diagram is a diagram that traces the
path that light takes in order for a person to
view a point on the image of an object.

10. Differentiating Between
Types of Ray Diagrams.
• Rules for concave ray diagrams- Any
•
incident ray traveling parallel to the
principal axis on the way to the mirror will
pass through the focal point upon reflection.
Any incident ray passing through the focal
point on the way to the mirror will travel
parallel to the principal axis upon reflection.

11. Continued…..
•
•
Rules for convex ray diagrams- any
incident ray traveling parallel to the
principal axis on the way to a convex mirror
will reflect in such a manner that its
extension will pass through the focal point.
Any incident ray traveling towards a convex
mirror such that it extentions passes through
the focal point will reflect and travel parallel
to the principal axis.
