The point where » = +A is typically called the \crest" of the wave and the point where » = ¡A is called the \trough" of the wave.2 The distance from crest to crest (or trough to trough) is called the \wavelength," the distance between points on the wave which have the same phase at the same instant of time.
Which of the settings—amplitude, frequency, damping, or tension—changes the amplitude of the wave as it propagates? What does it do to the amplitude? Frequency; it decreases the amplitude of the wave as it propagates.

Intensity of a wave vs. amplitude. Intensity of a wave’s radiation at a certain distance from the source. Transmitted intensity of light incident on a polariser (Malus’s law).
This article is an introduction to the physics of waves as it relates to sound propagation. While it does not require a background in physics to understand, it is assumed that the reader has at least high school level linear algebra, calculus, and trigonometry.
A wave is a disturbance that remains unchanged while it moves with some y^ constant velocity. There are water waves, waves on strings, sound waves, (a) x^. earthquake waves, radio waves, light waves, radar waves, X-rays, etc. In the present unit we shall discuss the most basic properties common to all kinds of waves.
