Knowledge
Students know:
- The concept of the superposition principle.
- The relationship among frequency, wavelength and speed.
- The relationship between frequency and pitch.
- The relationship between wavelength and color.
Skills
Students are able to:
- Illustrate/model the concept of the superposition principle responsible for wave patterns.
- Illustrate/model waveforms to show interference.
- Illustrate/model waveforms to show standing waves.
- Explore wave behavior.
- Make predictions about wave behavior as applied to phenomena such as Doppler and SONAR.
- Locate information from multiple sources.
Understanding
Students understand that:
- When waves interfere they form wave patterns predicted by the law of superposition.
- Wave behavior, known as the Doppler Effect, can be used to determine the relative speed of objects producing or reflecting waves.
