X-ray

(electromagnetic radiation, wavelength .01 to 10 nanometers)

An X-ray is Electromagnetic Radiation with Wavelength in the range of 0.01nm-10nm. They lie between Ultraviolet and Gamma Rays.

Lower energy/Frequency X-Rays, toward the ultraviolet end, are termed Soft and higher energy/frequency, toward the gamma rays end are termed Hard. The intervening line is about 0.1-to-0.2nm or 5-to-10keV.
