1. Images in Curved Mirrors

2. Learning goals
We are learning to identify the difference between curved mirrors.
We are learning the parts of curved mirrors.
We are learning to draw ray diagrams in curved mirrors.

3. Types of Curved Mirrors:
Concave:
Inner surface of curved mirror is reflective
Convex:
Outer surface of curved mirror is reflective

6. Terminology Centre of Curvature (C) Principal Axis (PA) Vertex (V)
Centre of the sphere whose surface is used to make the mirror
Principal Axis (PA)
Line going through the centre of curvature and the centre of the mirror
Vertex (V)
Point where the PA intersects the mirror

7. terminology
Focus (F)
The point where parallel light rays come together or converge on a concave mirror
Half way between C and V

8. Concave Mirrors
Light rays CONVERGE in front of mirror and meet at focus
Produce various images depending on the location of the object

9. Real Image
An image that can be seen on a screen as a result of light rays actually arriving at the location

10. Convex Mirror
Light rays DIVERGE on the mirror and meet at a virtual focus behind the mirror
Large viewing area but can cause some distortion

11. Learning goals
We are learning to identify the difference between curved mirrors.
We are learning the parts of curved mirrors.
We are learning to draw ray diagrams in curved mirrors.

12. Now …
Let’s do some ray diagrams!!!
