aaltopituuksien
Aaltopituuksien, meaning "wavelengths" in Finnish, refers to the spatial period of a periodic wave, the distance over which the wave's shape repeats. It is commonly denoted by the Greek letter lambda (λ). Wavelength is an intrinsic property of a wave and is inversely proportional to its frequency. For a wave traveling at a certain speed, a longer wavelength corresponds to a lower frequency, and a shorter wavelength corresponds to a higher frequency. The relationship can be expressed by the formula v = fλ, where v is the wave speed, f is the frequency, and λ is the wavelength.
Different types of waves have distinct wavelength ranges. For example, electromagnetic waves, such as visible light,
