Key concepts
CH 25: Vibrations & Waves
Honors:
Use Hewitt CH 38 as a resource to report on the wave/particle duality of light. Describe how Einstein’s discovery of the photoelectric effect informs us about how light works, and using evidence from completing the PhET Photoelectric Effect simulation. |
