Georgia HomeroomS8P4Electromagnetic vs. Mechanical Waves
Obtain, evaluate, and communicate information to support the claim that electromagnetic (light) waves behave differently than mechanical (sound) waves.
Appears in: Science, Grade 8
Expectations
S8P4.aAsk questions to develop explanations about the similarities and differences between electromagnetic and mechanical waves.
S8P4.bConstruct an explanation using data to illustrate the relationship between the electromagnetic spectrum and energy.
S8P4.cDesign a device to illustrate practical applications of the electromagnetic spectrum (e.g., communication, medical, military).
S8P4.dDevelop and use a model to compare and contrast how light and sound waves are reflected, refracted, absorbed, diffracted or transmitted through various materials.
S8P4.eAnalyze and interpret data to predict patterns in the relationship between density of media and wave behavior (i.e., speed).
S8P4.fDevelop 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.
S8P4.gDevelop and use models to demonstrate the effects that lenses have on light (i.e., formation an image) and their possible technological applications.
