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.
