Wavelengths

Wavelength refers to the distance between consecutive points of similar phase in a wave, such as the crest of a wave. It represents how long one cycle of the wave lasts before it repeats. In practical terms, longer wavelengths correspond to lower energy waves, like radio waves, which can travel long distances, while shorter wavelengths, like gamma rays, carry more energy and have higher frequencies. Wavelength helps us understand different types of waves—such as light, sound, or radio waves—and how they behave, interact with objects, and transmit information.
