The following can be used as a measure for the wavelength of an electromagnetic wave:
- trough to trough distance
- crest to crest distance
The wavelength is defined as the distance over which the wave's shape repeats, which is typically measured from one crest to the next crest or from one trough to the next trough.
"Crest to trough distance" generally does not represent a measure of wavelength, as it measures the distance vertically between a peak and a valley rather than horizontally across the wave cycle. "Trough to crest distance" is also not a standard way to measure wavelength for similar reasons.
