What is Wavelength?

Wavelength, in the context of physics and engineering, refers to the distance between successive crests or troughs of a wave. It is commonly used to characterize electromagnetic radiation (like light and radio waves) and other wave phenomena such as sound waves. Different wavelengths correspond to different types of electromagnetic radiation, for example, radio waves have long wavelengths, while gamma rays have very short wavelengths. Understanding and manipulating wavelengths is crucial in various applications, including telecommunications, spectroscopy, and medical imaging.
