4. What Is Light? Part of Electromagnetic Spectrum Very small portion Energy waves- travel in vacuum

5. Photons Governed by quantum mechanics Exhibit wave particle duality Properties of waves AND particles Confusing as administrator's speech

6. For Our Purposes Light shows characteristics of waves Has three properties Easily demonstrated in class

7. Reflect Refract Absorb Bounce Bend Stop Three Properties Of Light

8. Reflection Angle In = Angle Out

9. Refraction Intact Light  passes between materials Best example is a hand lens http://cnps.org/store_images/handlens1.jpg

10. Focal Length

13. Refraction  Color Light  passes between materials Colors refract at different angles

14. Classic Experiment Sunlight  passes through prism Colors refract at different angles Herschel discovers Infrared light in 1800

16. Absorption White Light  Roy G. Biv Red Surface White Light In  Roy G. Biv out
