Light and Optics
S8P4. Obtain, evaluate, and communicate information to support the claim that electromagnetic (light) waves behave differently than mechanical (sound) waves.
- 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.) - Construct an explanation using data to illustrate the relationship between the electromagnetic spectrum and energy.
- Design a device to illustrate practical applications of the electromagnetic spectrum (e.g., communication, medical, military).
- 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.) - Analyze and interpret data to predict patterns in the relationship between density of media and wave behavior (i.e., speed).
- 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.
- Develop and use models to demonstrate the effects that lenses have on light (i.e., formation an image) and their possible technological applications.
