No, an X-ray is not a mechanical wave. An X-ray is an electromagnetic wave. However, in polar molecules, an X-ray can cause the molecule to vibrate rapidly, just like a microwave oven can.
X-radiation (composed of X-rays) is a form of electromagnetic radiation. Most X-rays have a wavelength ranging from 0.01 to 10 nanometers, corresponding to frequencies in the range 30 petahertz to 30 exahertz (3Ã1016 Hz to 3Ã1019 Hz) and energies in the range 100 eV to 100 keV.
