Knowledge and Skills Statement

Force, motion, and energy. The student knows how energy is transferred through waves.
Glossary terms and definitions are consistent across kindergarten through high school in the TEKS Guide. The definitions are intended to give educators a common understanding of the terms regardless of what grade level they teach. Glossary definitions are not intended for use with students.

the height of a wave measured from rest to the top of the crest or bottom of the trough of the wave; often used to describe volume of sound or intensity of light

 a measurable quantity that describes how much change can occur within a system

the number of waves that pass a given point in a specified amount of time (usually 1 second), measured in hertz (Hz); the pitch of a sound or the color of light

a type of wave in which the particles oscillate perpendicular to the direction in which the energy propagates

a disturbance or variation that transfers energy progressively from point to point with or without a medium, without transferring matter

distance between the same point on two successive waves; distance from crest to crest or trough to trough for two consecutive waves

Summary: This article supports teacher understanding by explaining the motion of waves and sharing a model of the various components of a wave. Details on a variety of waves, how they propagate, and whether a medium is required to carry the wave are provided.
