  1. Refraction Power-Point

  2. Definition • Refraction- the bending of a wave or particle as it passes from different mediums

  3. Application • A fish appears higher than it actually is…

  4. Bending Toward the Normal • When light goes from a less dense to more dense medium, it is bent toward the normal. This is an example of air going to plexiglass.

  5. Bending Away from the Normal • When light passes from plexiglass to air, it bends away from the normal.

  6. Total Internal Reflection • Only occurs when light goes from more dense to less dense. • Three cases: • (1) Refracts- bends away from normal (o-43o) • (2) Critical angle- prism • (3) Reflection

  7. Total Internal Reflection

  8. Applications of Refraction • Fiber optics, polar bear skin, sparkling of diamonds

  9. Lab…Semicircular Prisms

  10. Rectangular Prism

  11. Right Triangle Prism

  12. Equilateral Triangle Prism

  13. Pink Floyd…Which is correct?
