List of Electromagnetic Spectrum in Ascending order of wavelength

 Electromagnetic spectrum in ascending order of wavelength along with approximate numerical values: Gamma rays: Wavelengths range from less than 0.01 nanometers to about 10 picometers (pm). X-rays : Wavelengths range from about 0.01 to 10 nanometers. UV (Ultraviolet) : Wavelengths range from about 10 to 400 nanometres. Visible: Wavelengths range from about 400 to 700 nanometers. Infrared : Wavelengths range from about 700 nanometers to 1 millimeter. Microwaves : Wavelengths range from about 1 millimeter to 1 meter. Radio and TV waves: Wavelengths are typically greater than 1 meter.
