High School (SCI) Physical Science Standards
[PS4] Waves and Their Applications in Technologies for Information Transfers

##### SCI-HS.PS4.01 Use mathematical representations to support a claim regarding relationships among the frequency, wavelength, and speed of waves traveling in various media.

Clarification Statement: Physical Science/Physics: Examples of data could include electromagnetic radiation traveling in a vacuum and glass, sound waves traveling through air and water, and seismic waves traveling through the Earth.
Disciplinary Core Ideas
PS4.A: Wave Properties The wavelength and frequency of a wave are related to one another by the speed of travel of the wave, which depends on the type of wave and the medium through which it is passing.
