GSE S8P4 | Electromagnetic and Mechanical Waves
Obtain, evaluate, and communicate information to support the claim that electromagnetic (light) waves behave differently than mechanical (sound) waves.
  • a. Ask questions to develop explanations about the similarities and differences between electromagnetic and mechanical waves. (Clarification statement: Include transverse and longitudinal waves and wave parts such as crest, trough, compressions, and rarefactions.)
  • b. Construct an explanation using data to illustrate the relationship between the electromagnetic spectrum and energy.
  • c. Design a device to illustrate practical applications of the electromagnetic spectrum (e.g., communication, medical, military).
  • d. Develop and use a model to compare and contrast how light and sound waves are reflected, refracted, absorbed, diffracted or transmitted through various materials. (Clarification statement: Include echo and how color is seen but do not cover interference and scattering.)
  • e. Analyze and interpret data to predict patterns in the relationship between density of media and wave behavior (i.e., speed).
  • f. Develop and use a model (e.g., simulations, graphs, illustrations) to predict and describe the relationships between wave properties (e.g., frequency, amplitude, and wavelength) and energy.
  • g. Develop and use models to demonstrate the effects that lenses have on light (i.e., formation an image) and their possible technological applications.

Essential Questions

1. What are waves and what are the two broad types of waves?
2. ​Which properties of waves can change?
3. How do sound waves travel and behave?
4. How does the speed of sound waves changes as they change mediums?
5. How do light waves travel and behave?
6. How do lenses change light waves and the image that may appear?​
7. How is the amount of energy a wave carries reflected in the frequency or amplitude of the wave?
