What is the radiation source for x-ray waves?

X-rays are a form of electromagnetic radiation, just like visible light, but with much shorter wavelengths. They are produced when high-energy electrons are suddenly decelerated. This can happen when electrons collide with a solid target, such as a metal, or when they are accelerated in a magnetic field.

The most common source of x-rays is an x-ray tube. In an x-ray tube, electrons are emitted from a cathode and accelerated towards an anode. The anode is made of a heavy metal, such as tungsten, which stops the electrons and causes them to decelerate. This deceleration produces x-rays.

X-rays are also produced by natural sources, such as the sun and other stars. In these cases, x-rays are produced when high-energy electrons in the sun's atmosphere interact with the sun's magnetic field.

X-rays can be used for a variety of purposes, including medical imaging, security screening, and industrial testing.
