Summary
| Description |
English: This diagram describes the relationships between the various properties of harmonic waves: frequency, period, wavelength, angular frequency, and wavenumber. The properties are organized in three axes: * linear properties on the left, and their angular equivalents on the right; * frequency properties on the top, and their periodic reciprocals on the bottom; * temporal properties at the front, and their spatial equivalents at the back. |

LaTeX source code
The source code below was developed interactively using the ShareLaTeX online editor. It makes use of the xymatrix package, and uses a command definition from TeX.StackExchange do draw the barred lambda character.
To generate the SVG image, the LaTeX document was exported from ShareLaTeX as a PDF file, converted to SVG using Online-Convert.com, and cleaned-up (grouping related objects, tweaking positioning of some elements) using Inkscape.
