WebThe approximate wavelength range of the X-ray portion of the electromagnetic spectrum, 10 −8 to 10 −12 metre, corresponds to a range of photon energies from about 100 eV ( electron volts) to 1 MeV (million electron volts). Applications
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 … Ver más 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 Ver más X-ray photons carry enough energy to ionize atoms and disrupt molecular bonds. This makes it a type of ionizing radiation, and therefore harmful to … Ver más X-rays interact with matter in three main ways, through photoabsorption, Compton scattering, and Rayleigh scattering.
