More x-ray essay topics when an x-ray interacts with the matter it incidents on, it transfers energy by potentially two processes namely ionization and excitation. In some cases, it may lead to secondary emission of visible light upon its interaction with matter when an x-ray photon collides with an atom, the atom may absorb the energy of the photon and boost an electron to a higher orbital level or if the photon is very energetic.
