This Chandra X-ray Observatory website gives a brief history on the discovery of X-rays and how they are produced. There is also information on other forms of light. This website includes illustrations and information on X- ray production, inverse Compton scattering, atomic emission, and synchrotron radiation. There are also links to learn more about the differences between x-ray astronomy and medical x-rays, and to a word search for x-rays and light.
