Where are x-rays made? - Answer-in the electron shell structure of an atom What is Bremsstrahlung radiation? - Answer-energetic electrons pass very near the nucleus of an atom. The strong forces of th positive charged atom causes the negatively charged electron to decelerate; the path of the electron is changed, and some of the kinetic energy of the electron is lost, and converted into x-rays what is characteristic x-ray radiation? - Answer-following the ionization of an atom that leaves...

Electron Gun Model Answer - correct answer-- Low voltage supply heats filament causes thermionic emission/ electrons have enough energy to leave - Electrons are repulsed from the cathode (filament) and attracted towards the anode - This electric field causes electrons to accelerate - There is a hole in the anode which creates a beam for electrons that pass through - Electrons are then fired through a vacuum (to stop interfering particles) onto a fluorescent screen Photo Electric E...
