wavelength

Wavelength refers to the distance between successive crests or troughs in a wave, such as light or sound waves. It measures how far the wave travels before repeating its pattern. Wavelength determines the wave's properties; for example, in light, longer wavelengths correspond to colors like red, while shorter wavelengths relate to blue or violet. In sound, wavelength influences pitch—the longer the wavelength, the lower the pitch. Wavelength is a fundamental aspect of wave behavior, helping us understand phenomena like color, sound, and even how radio signals travel.
