Millimeter waves are a type of radiofrequency electromagnetic radiation with wavelengths between 0.1 and 10 millimeters long. Because they are susceptible to absorption by water in the atmosphere, they travel short distances only. Despite this limitation, their short wavelength makes them a useful technology for small-distance applications. Examples include short-range, secure wireless communication and automotive-radar technology, which lets self-driving cars sense their environment.
