Wavelength is determined for a given wave by measuring the distance between two consecutive corresponding points on the wave, such as the peak-to-peak distance or the trough-to-trough distance. This distance can be measured in various units such as meters, nanometers, or micrometers, depending on the type of wave being analyzed. The wavelength of a wave can also be calculated using the wave's frequency and speed, as wavelength = speed / frequency.
