WebMost X-rays have a wavelength ranging from 0.01 to 10 nanometers (3×10 16 Hz to 3×10 19 Hz), corresponding to energies in the range of 100 eV to 100 keV. X-ray wavelengths are shorter than those of UV rays and typically longer than those of gamma rays. The distinction between X-rays and gamma rays is not so simple and has changed in recent ...
