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.
As the wavelengths of light decrease, they increase in energy. X-rays have smaller wavelengths and therefore higher energy than ultraviolet waves. We usually talk about X-rays in terms of their energy rather than wavelength.This is partially because X-rays have very small wavelengths.It is also because X-ray light tends to act more like a particle than a wave.t doesn't hurt at all-you can't feel X-rays. Because your bones and teeth are dense and absorb more X-rays then your skin does, silhouettes of your bones or teeth are left on the X-ray film while your skin appears transparent.
