Presentation Transcript

  1. Plane Mirrors • Flat mirror that is most common. • The image we see in a mirror is called a virtual image. [http://sol.sci.uop.edu/~jfalward/reflection/castlemirror.jpg]

  2. Virtual image in a plane mirror is inverted. [http://sol.sci.uop.edu/~jfalward/reflection/castlemirror.jpg] Click here for virtual image demo

  3. When viewed in a rear-view mirror, “Ambulance” is correct! [http://www.ohmvfiredept.org/137_front.jpg]

  4. Concave Mirrors • Surface of mirror curves inward. • Light waves will reflect off of surface and combine at a focal point. [http://sol.sci.uop.edu/~jfalward/reflection/twoparallelraysconcave.jpg]

  6. Concave Mirrors • Can create a virtual image if the object is within the focal length. • Magnifies the object… [http://www.wfu.edu/physics/demolabs/demos/avimov/optics/concave_mirror_large/concavemirror.JPG]

  7. Concave Mirror Ray Diagram Object Distance < Focal Length Incoming Light Waves Reflected Light Waves Virtual Image: Upright & Magnified

  8. Concave Mirrors • Can create a real image if the object is twice the focal length. [http://library.thinkquest.org/26162/fig4-6.gif]

  9. Concave Mirror Ray Diagram Object Distance > Focal Length Incoming Light Waves Reflected Light Waves Real Image: Upside down (Size can change!)

  10. Convex Mirrors • Surface of mirror curves outward. • Shrink images, but allow you to see more area.

  11. Convex Mirrors • “Objects in mirror are closer than they appear” • Only create virtual images [http://www.geocities.com/srivathsajoshi/cautionmessage.jpg]

  12. Convex Mirror Ray Diagram Object at Any Location Incoming Light Waves Virtual Image: Smaller & Upright Reflected Light Waves
