  1. Images in Curved Mirrors all mirrors are not flat...

  2. Can you think of examples of curved mirrors? Flashlights Makeup mirrors Security mirrors

  3. 2 Types of Curved Mirrors Pg 496 Concave Convex

  4. Concave Mirror Also known as a converging mirror Caves in Middle bulges away from you

  5. Convex Mirror Also known as a diverging mirror Caves OUT Middle bulges TOWARDS you

  6. Concave Mirrors Pg 496 Reflected rays always converge in a concave mirror This is why they are also called converging mirrors

  7. TERMS

  8. Centre of Curvature (C) Pg 496 Centre of the sphere It is 2 times the length of the focus (F)

  9. Focus (F) Pg 496 A point where parallel light rays come together (converge)

  10. Principle Axis (P.A.) Pg 496 A line through the centre of curvature to the midpoint of the mirror

  11. Vertex (V) Pg 496 The point where the principle axis meets the mirror

  12. How to locate the Image in a Concave Mirror From the top of the object, draw a light ray parallel to the P.A. When it hits the mirror, it should reflect through the focus

  13. How to locate the Image in a Concave Mirror From the top of the object, draw a light ray through the focus When it hits the mirror, it should reflect back, parallel to the P.A.

  14. How to locate the Image in a Concave Mirror Where the two light rays intersect (cross) that represents the top of the image Draw in your image

  15. Try it out: Draw the focus 4 cm from the vertex. So this means C will be 8 cm from the vertex (2F). Find the reflected image.

  16. Real Image Virtual Image • an image that is formed IN FRONT of the mirror • The image can be projected on a screen • an image that is formed BEHIND the mirror • The image CANNOT be projected on a screen

  17. Summary of Images in a Concave Mirror Pg 499
