MS-PS4. Waves and Their Applications in Technologies for Information Transfer
Students who demonstrate understanding can:
MS-PS4-1. Use mathematical representations to describe a simple model for waves that includes how the amplitude of a wave is related to the energy in a wave.
MS-PS4-2. Develop and use a model to describe that waves are reflected, absorbed, or transmitted through various materials.
