Enduring Understandings

 * There is a spectrum of electromagnetic wave energy, with varied frequencies and wavelengths.
 * The transmission and absorption of electromagnetic waves varies, and can be used for many purposes.

Prior Learning (from S8 Anchors)
S8.C.2.1 Describe energy sources, transfer of energy, or conversion of energy.
 * S8.C.2.1.1 Distinguish among forms of energy (e.g., electrical, mechanical, chemical, light, sound, nuclear) and sources of energy (i.e., renewable and nonrenewable energy)
 * S8.C.2.1.2 Explain how energy is transferred from one place to another through convection, conduction, or radiation.
 * S8.C.2.1.3 Describe how one form of energy (e.g., electrical, mechanical, chemical, light, sound, nuclear) can be converted into a different form of energy.
