Summary

[edit]
Description
English: The harmonics of lightwaves drawn to scale, showing how the different waves interact with each other. The λ/2 (1/2 wavelength) harmonics are perfectly in sync with each other, but all other colors in the visual spectrum fall between λ and λ/2. Wavelengths that are separated by λ/4 are opposites, falling across from each other on the color wheel. (ie: Red is opposite of green, orange is opposite of blue, and yellow is opposite of violet.) Image was generated using Tikz and the resulting PDF was converted to SVG.

This file contains additional information such as Exif metadata which may have been added by the digital camera, scanner, or software program used to create or digitize it. If the file has been modified from its original state, some details such as the timestamp may not fully reflect those of the original file. The timestamp is only as accurate as the clock in the camera, and it may be completely wrong.
