X-ray

Electromagnetic radiation that has a very short wavelength, emitted from a substance when it is attacked by a line of electrons in a vacuum. Machines are able to produce this, and they are known as x-ray machines. They are useful in geology and mineralogy for the study of the chemical constituents of rocks and minerals.
