What does wavelength mean?
The distance between two consecutive points in phase on a wave, measured in units such as metres or inches. The length of a wave, typically measured in a direction perpendicular to the direction of propagation.
Example
"The wavelength of the light emitted by the laser was measured to be 632 nanometres."
