Objective:
– Demonstrate properties of standing waves, including the concept of a resonance frequency and the medium dependence of wave speed.
– Demonstrate the idea of sampling, and how this impacts the information we obtain.

- Elastic String
- Two leads
- Hanging masses (entire set)
- Two rings stands (that clamp to the table)
- Pulley (e.g., the ones from ST2)
