Detailed explanation-1: -Summary of steps Electrons released from filament. Tube voltage is applied across the x-ray tube. Electrons, therefore, are accelerated towards positively charged anode, which gives them a certain energy. The electrons strike the anode and the energy released via interaction with the anode atoms produces x-ray photons.
Detailed explanation-2: -Producing X-rays in a tube generally requires three essential steps: the proper assembly of a tube with a source of electrons, a means to accelerate the electrons, and then decelerate the electrons.
Detailed explanation-3: -Most X-rays have a wavelength ranging from 10 picometers to 10 nanometers, corresponding to frequencies in the range 30 petahertz to 30 exahertz (3×1016 Hz to 3×1019 Hz) and energies in the range 145 eV to 124 keV. X-ray wavelengths are shorter than those of UV rays and typically longer than those of gamma rays.
