Use mathematical representations to support a claim regarding relationships among the period, frequency, wavelength, and speed of waves traveling and transferring energy (amplitude, frequency) in
various media.
Clarification statement: Examples of data could include descriptions of waves classified as transverse, longitudinal, mechanical, or standing, electromagnetic radiation traveling in a vacuum and glass, sound waves traveling through air and water, seismic waves traveling through Earth, and direction of waves due to reflection and refraction.
Assessment boundary: Assessment is limited to algebraic relationships and describing those relationships qualitatively.
PLDs communicate the knowledge and skills expected of students to demonstrate proficiency in each Learning Standard. NYS assessments classify student performance into one of five levels.
Plan and conduct an investigation and use mathematical representations to evaluate claims regarding the relationships among the period, frequency, wavelength, and speed of waves traveling and transferring energy in various media.
Use mathematical representations to support a claim regarding relationships among the period, frequency, wavelength, and speed of waves traveling and transferring energy (amplitude, frequency) in various media.
Given data, model(s), and/or a mathematical representation, determine the period, frequency, wavelength, or speed of a wave or electromagnetic radiation (photon) traveling and transferring energy in a medium, or use mathematical relationships and a ruler and protractor to construct the reflected and/or refracted ray(s) to show the direction of a wave as it hits a boundary, or determine the index of refraction.
Use words, diagrams, and/or graphs to represent the mathematical relationships among the period, frequency, wavelength, and/or speed of waves in a medium, or use mathematical relationships to determine the direction of a wave as the wave hits a boundary (reflection and/or refraction), or given data, model(s), and/or a mathematical representation, compare the phase of points at positions on the wave or the relative amount of energy transferred due to amplitude or frequency, or determine the amount of energy transferred due to the frequency of electromagnetic radiation (photon).
Draw a model of a wave with given characteristics or identify the characteristics of a given wave traveling and transferring energy in a medium (period, frequency, wavelength, amplitude, speed, and/or type), or identify the change in characteristics of a wave as the wave hits a boundary.

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.
Crosscutting Concepts
Cause and Effect
Empirical evidence is required to differentiate between cause and correlation and make claims about specific causes and effects.
