  1. Mirrors why bother?

  2. 3 types of mirrors Flat (plane, infinite) Concave (caved in, converging) Convex (vexed out, diverging)

  3. Plane Mirrors Is this kind of plane mirror possible?

  4. Curved Mirror Terms focal point= r/2 (horizontal light focuses here) principal axis C f The Center of Curvature or radius “r”

  5. Real vs. Virtual Images Real Image: Light from an object reflects off mirror, converges (focuses) back on same side of mirror(you see it and can feel it or re-project it) Virtual Image: Light reflects off mirror but diverges (scatters) so it appears on the opposite side of mirror(you see it, but only in your mind- it’s not there! Real Image Object Virtual Image Object

  6. Virtual images are posers!

  7. Real images are inverted always!

  8. C f 3 types of curved mirror pictures Concave- object further than focal pt. Concave- object closer than focal pt. Convex object anywhere C f C f

  9. Summary: Concave Object far from mirror: real, inverted, smaller Object very close: virtual, upright, larger

  10. Summary: Convex Mirrors No matter where you put the object,…. Only get……virtual, upright, smaller images

  11. The end- see it again on my web site! Hubble Telescope
