Overview

The more we learn about waves, the more we learn about a lot of things in physics. Waves can help explain everything from earthquakes to music. This video explores waves and how they travel.

SC15.PHYS.8

Investigate the nature of wave behavior to illustrate the concept of the superposition principle responsible for wave patterns, constructive and destructive interference, and standing waves (e.g., organ pipes, tuned exhaust systems).

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.
