Definition:Stationary Wave

Definition

A stationary wave is a wave whose wave profile does not move forward.

This article is complete as far as it goes, but it could do with expansion. In particular: Coulson's exposition is imprecise and somewhat woolly here. I am going to need to expand my reading list here, as Coulson does not implement the level of precision we like on $\mathsf{Pr} \infty \mathsf{fWiki}$. You can help $\mathsf{Pr} \infty \mathsf{fWiki}$ by adding this information. To discuss this page in more detail, feel free to use the talk page. When this work has been completed, you may remove this instance of {{Expand}} from the code. If you would welcome a second opinion as to whether your work is correct, add a call to {{Proofread}} the page.

Node

The nodes of a stationary wave are the points in space at which the disturbance is always zero.

Antinode

The antinodes of a stationary wave are the points in space at which the amplitude is a maximum.

Also known as

In popular parlance, a stationary wave is often referred to as a standing wave.
