🔬 Grade 7 • 📡 Waves, Light, and Information Systems
Waves, Light, and Information Systems
Explain how waves carry energy and information, and how wavelength, frequency, reflection, and refraction help scientists describe light and wave behavior.
📋 What You'll Learn
- 1 Use models to describe wavelength, frequency, and amplitude in waves
- 2 Explain how waves can carry energy and information
- 3 Describe reflection and refraction as predictable behaviors of light
- 4 Compare how different wave properties affect what scientists observe
