Mirror ppt

  1. 1. Mirrors (Concave/ Convex) By:Dallas Smith and Breanna Brisley
  2. 2. Objective • Distinguish between the different types of mirrors. • Describe a simple ray diagram. • Distinguish between real and virtual images.
  3. 3. Introductory Today we will be talking about… Mirrors • o • • o Concave Convex Simple ray diagrams Images o o Virtual Real
  4. 4. Concave Mirrors • • A concave mirror is a mirror that has a slightly inward curve like the inside of a spoon. The curved surface focuses parallel rays from a great distance into a single point for enhanced intensity.
  5. 5. Concave Mirrors • • The image you see from the mirror is either real (inverted) or virtual (upright). The image depends on the objects distance from the surface to the mirror.
  6. 6. Examples of Concave Mirrors • Headlights of a car o • Dentist mirror o • the source of light is placed at the focus of the concave reflector focus light on the tooth to be examined Make-up mirrors o enlarges the image to be easier to see
  7. 7. Convex Mirrors • • A convex mirror curves outward like the back of a spoon. The image reflected from a convex mirror is smaller, upright, and virtual.
  8. 8. Examples of Convex Mirrors • Side-view mirror o • Security mirrors o • allows the driver to see more objects and a wider view of what’s behind used in malls, convenience stores, and supermarkets to view a large portion of people Camera phone o helps to aim correctly when taking a self- portrait
  9. 9. Simple Ray Diagram
  10. 10. Real vs. Virtual Images Real Image Virtual Image
  11. 11. Concave & Convex in real life.
