What is X-Ray?
High-energy electromagnetic radiation with wavelengths between 0.01 and 10 nanometers. X-rays are produced when high-speed electrons strike a metal target. They penetrate matter and are used in medical imaging, materials analysis, and X-ray crystallography to determine crystal structures.

Frequently Asked Questions
High-energy electromagnetic radiation with wavelengths between 0.01 and 10 nanometers. X-rays are produced when high-speed electrons strike a metal target. They penetrate matter and are used in medical imaging, materials analysis, and X-ray crystallography to determine crystal structures.
X-rays are used in medical radiography and computed tomography (CT) to image internal body structures. X-ray crystallography determines atomic-level structures of molecules including proteins and drugs. X-ray fluorescence (XRF) is used for elemental analysis in materials science and geology.
X-rays are ionising radiation that can damage DNA and increase cancer risk. Medical exposures are minimised through lead shielding, distance, and limiting exposure time. Radiation workers must comply with dose limits and use personal dosimeters.
The formula or notation for X-Ray is: X-ray: λ = 0.01-10 nm; E = hc/λ; Bragg: 2d sinθ = nλ
