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.
An x-ray is a form of electro magnetic radiation, with a wavelength of 10 to 0.001 nanometers (shorter than ultraviolet light).The letter 'X' comes from their initial discovery, when they were an unknown form of radiation and thus given the moniker 'X' to indicate 'unknown.'.he patient is positioned between the x-ray machine and the film. It is the x ray technician's job to properly align the patient in space in order to capture the appropriate 2-D plane. Areas not of interest should be appropriately shielded. After the beam is activated, the film is shown to the radiologist.
