X-ray is a form of electromagnetic radiation. Frequencies in the range 30 petahertz to 30 exahertz (3×10^16 Hz to 3×10^19 Hz) Energies in the range 100 eV to 100 keV. It a type of ionizing radiation, and therefore harmful to living tissue.

• X-ray is a form of electromagnetic radiation.
• Frequencies in the range 30 petahertz to 30 exahertz (3×10^16 Hz to
3×10^19 Hz)
• Energies in the range 100 eV to 100 keV.
