Science / Chemistry / X-Ray: A very high energy form of electromagnetic radiation (though not as high energy as gamma rays). X-rays typically have wavelengths from a few picometers up to 20 nanometers. X-rays easily penetrate soft tissue, which makes them useful in medical imaging and in radiation therapy.

X-Ray Spectrum

Science / Chemistry / X-Ray Spectrum: A set of characteristic x-ray frequencies or wavelengths produced by a substance used as a target in an x-ray tube. Each element has a characteristic x-ray spectrum, and there is a strong correlation MORE

X-Ray Tube

Science / Chemistry / X-Ray Tube: A cathode ray tube that focuses energetic streams of electrons on a metal target, causing the metal to emit x-rays. MORE

Occlusal X-Ray

Health / Dentistry / Occlusal X-Ray: An intraoral x-ray taken with the film held between the teeth in biting position. MORE

X-Ray Crystallography

Science / Chemistry / X-Ray Crystallography: Determination of three dimensional arrangement of atoms in a crystal by analysis of x-ray diffraction patterns. MORE

X-Ray Diffraction Pattern

Science / Chemistry / X-Ray Diffraction Pattern: Interference patterns created by x-rays as they pass through a solid material. Studying x-ray diffraction patterns gives detailed information on the three-dimensional structure of crystals, surfaces, MORE

X-Ray Diffraction

Science / Biology / X-Ray Diffraction: Technique utilized to study atomic structure of crystalline substances by noting the patterns produced by x-rays shot through the crystal. MORE
