1. X-ray (x-ray radiation)
Electromagnetic radiation with wavelengths between approximately .01 nanometers to 200 nanometers. These energy beams are powerful enough to penetrate most substances except heavy metals (such as gold and lead). X-rays are used to examine body parts; the x-rays are absorbed by tissues containing lots of calcium (bones, teeth, etc.) and thus x-ray films are useful for detecting fractures, misalignments, abnormal cavities, etc.

2. X-ray crystallography
A technique of determining a molecule's three-dimensional structure by analyzing the x-ray diffraction patterns of crystals made up of the molecule in question.

3. X-ray diffraction
Technique utilized to study atomic structure of crystalline substances by noting the patterns produced by x-rays shot through the crystal.
