Core Idea - Waves and Their Applications in Technologies for Information Transfer
[HS.PHY.4.5] - Communicate technical information about how some technological devices use the principles of wave behavior and wave interactions with matter to transmit and capture information and energy.* Clarification Statements: Emphasis is on qualitative information and descriptions. Examples of technological devices could include solar cells capturing light and converting it to electricity, medical imaging, and communications technology. Examples of principles of wave behavior include resonance, photoelectric effect, and constructive and destructive interference.
State Assessment Boundary: Band theory is not expected in state assessment.
[WCA.9-10.2] -
Write informative/explanatory texts, including the narration of historical events, scientific procedures/ experiments, or technical processes.
[HS.PHY.4.3] -
Evaluate the claims, evidence, and reasoning behind the idea that electromagnetic radiation can be described by either a wave model or a particle model, and that for some situations involving resonance, interference, diffraction, refraction, or the photoelectric effect, one model is more useful than the other. Clarification Statement: Emphasis is on qualitative reasoning and comparisons of the two models. State Assessment Boundary: Calculations of energy levels or resonant frequencies are not expected in state assessment.
