Aaltopituuksia
Aaltopituuksia, or wavelengths, are a fundamental property of waves, describing the spatial period of a periodic wave. It is the distance over which the wave's shape repeats. Imagine a wave on a string; the wavelength is the distance from one crest to the next crest, or from one trough to the next trough. This concept applies to all types of waves, including light waves, sound waves, and water waves.
The unit of wavelength is typically a unit of length, such as meters (m) in the International
The relationship between wavelength, wave speed, and frequency is a crucial one. For any wave, the speed
