The production of x-radiation

Webbwww.researchgate.net WebbProduction of X-rays. X-rays are short wavelength, high-frequency part of the electromagnetic spectrum. They have wavelengths in the range 10 −8 to 10 −13 m. X-rays are produced when fast-moving electrons rapidly decelerate and transfer their kinetic energy into photons of EM radiation.

WebbBremsstrahlung is electromagnetic radiation similar to x-radiation. It is emitted by a charged particle as it decelerates in a series of collisions with atomic particles. This mechanism is illustrated in Fig. 1.25, where a beta particle traveling through matter approaches a nucleus and is deflected by it.This deflection causes a deceleration of the … An X-ray, or, much less commonly, X-radiation, is a penetrating form of high-energy electromagnetic radiation. Most X-rays have a wavelength ranging from 10 picometers to 10 nanometers, corresponding to frequencies in the range 30 petahertz to 30 exahertz (3×10 Hz to 3×10 Hz) and energies in the … Visa mer Pre-Röntgen observations and research Before their discovery in 1895, X-rays were just a type of unidentified radiation emanating from experimental discharge tubes. They were noticed by scientists investigating Visa mer X-ray photons carry enough energy to ionize atoms and disrupt molecular bonds.
