The following measures can be used for the wavelength of an electromagnetic wave:
- **Crest to crest distance**
- **Trough to trough distance**
- **Crest to trough distance** (although less common, it can be used to find half of the wavelength)
The option "trough to crest distance" would not typically be used directly to measure wavelength since it represents the distance from the lowest point to the highest point, which is not a standard measure for wavelength. Wavelength is usually defined as the distance between two successive crests or two successive troughs.
