which electromagnetic has the shortest wavelength
Radio waves radio waves: Low frequency electromagnetic radiation used to transmit information such as television and radio programmes. have the lowest frequencies and longest wavelengths, while gamma waves have highest frequencies and shortest wavelengths. The wavelengths vary across the electromagnetic spectrum from about 10â15 m to more than 104 m. Page: 1  1. 2  2. 3  3. 4  4. 5  Back. 6  Next.
The wavelength of UV rays is shorter than the violet end of the visible spectrum but longer than the X-ray. UV in the very shortest wavelength range (next to X-rays) is capable of ionizing atoms (see photoelectric effect), greatly changing their physical behavior.
