A progressive wave is a type of wave that transfers energy without transferring material. Intensity is the power (energy transferred per unit time) per unit area, and can be calculated using the equation below: I = P. A. Where P is the power and A is the area.

A wave is a spatial form that translates in space while maintaining its shape. In general, a wave traveling in the x-direction can be represented by the function of the form f(˘), where ˘= x ct x
A stationary wave is formed from the superposition of 2 progressive waves , travelling in opposite directions in the same plane, with the same frequency, wavelength and amplitude. No energy is transferred by a stationary wave .
To find the amplitude: The y-axis of the CRO will show the displacement of the wave. The voltage/divisions setting will give the scale of the y axis. Each division will correspond to a stated voltage. Ensure the wave fills as much vertical space on the screen as possible by changing the voltage/div. .
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.
