Day 9 was a continuation of our exploration of waves. The class time was divided into two main activities:
- Working in groups on conceptual exercises related to waves (drawing waves, ranking them based on various properties, etc.), led by me.
- Carrying out a more systematic study of waves on a slinky, which included quantitative measurements of the speed of a wave pulse, led by my colleague Fred Wirth who has offered to lend a helping hand this semester and who designed and coordinated this portion of the class.
At the end, we discussed as a class the solutions to some of the conceptual exercises.
