2. Today’s Agenda
Refraction notes
Final Review

3. Refraction
Refraction: The change in direction of a wave as it passes the boundary of two different mediums where the wave changes speed

4. Light in Different Mediums
Light changes speed when it travels through a different medium
Light traveling from a less to more optically dense medium it slows down
- Light bends toward the normal
Light traveling from a more to less optically dense medium it speeds up
- Light bends away from the normal

5. Refraction of Light

6. Optical Densities Vacuum of Space Air Ice Water Glass Diamond Less
More

7. Refraction of Light

8. Properties of Plane or Flat Mirrors
As objects (or you) move away from the mirror
Have the same amount of reflection
Less detail, because the object appears further away.

9. Major Topics of the Final
Work and Power
Conservation of Energy
Waves
Sound
Light Reflection and Refraction
Electromagnetic Waves
(Electromagnetic Induction)

10. Final Review Due next Wednesday 5/20/15
Everyone needs to complete the review
Grades are updated except for “Refraction Lab” and “Mirror Image” Activity
