Unit 5 Day 2: Photoelectric Effect
1. Review experiments showing light as a wave:
a. Polarization
b. Double slit interference & single slit diffraction
c. Interferometers & thin film interference
2. What would happen in these experiments if light were a tiny particle instead of a wave?
3. Einstein history
4. www.explorelearning.com – photoelectric effect simulator:
5. IS LIGHT A PARTICLE OR WAVE? With your partner for the lab, discuss hypothesis.
6. Read through the handout carefully. It is quite technical – make sure that you underline
things you don’t understand and write out a list of questions for the TA.
7. Homework: Figure out where you’re going, and how you’re getting there & back to school.
