Electromagnetic Radiation - NASA waves

Introduction

Applications

NGSS Performance Expectations

MS-PS4-1. Wave Model

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. Wave Properties

Develop and use a model to describe that waves are reflected, absorbed, or transmitted through various materials.

MS-PS4-3. Data Transmission

Integrate qualitative scientific and technical information to support the claim that digitized signals are a more reliable way to encode and transmit information than analog signals. 

HS-PS4-1. Wave Equation

Use mathematical representations to support a claim regarding relationships among the frequency, wavelength, and speed of waves traveling in various media. 

HS-PS4-2. Digital Transmission

Evaluate questions about the advantages of using digital transmission and storage of information. 

HS-PS4-3. Wave/Particle Duality

Evaluate the claims, evidence, and reasoning behind the idea that electromagnetic radiation can be described either by a wave model or a particle model, and that for some situations one model is more useful than the other.

HS-PS4-4. Absorption

Evaluate the validity and reliability of claims in published materials of the effects that different frequencies of electromagnetic radiation have when absorbed by matter.

HS-PS4-5. Information and Energy

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.
