WebHow far can X-rays Travel Air? Their characteristic wavelengths and frequencies can be demonstrated and measured through the interference effects that result from the overlap of two or more waves in space. X-rays also exhibit particle-like properties; they can be described as a flow of photons carrying discrete amounts of energy and momentum.
