1. Watch Crash Course Physics #37 at youtube.com/watch?v=K40lNL3KsJ4 (Maxwell's Equations) Describe two or three key ideas and at least two mathematical formulae and what they mean.

2. Watch the video at youtube.com/watch?v=rB83DpBJQsE (Divergence and curl) by 3Blue1Brown, which shows with visualizations important concepts of wave and fluid motion in physics. Explain two or three key ideas and at least one mathematical formula and what it means.

3. Watch the GPB Physics in Motion Unit 6, Segment F video (Electromagnetic Wave Properties). Write down at least three concepts given in the video that supplement yet do not duplicate the material presented in the video lecture: at least one between 0:01 and 4:00, one between 4:01 and 8:00, and one between 8:01 and the end of the Segment F video. https://www.gpb.org/physics-in-motion/unit-6/electromagnetic-wave-properties

4. Watch the video youtube.com/watch?v=HAeDBLUT9JA (Is light a wave or a particle?) by Dr. Becky. Explain at least three things that you found interesting.
