Question

how do x-ray absorption and production differ from UV-Vis production and absorption?

Answer 1

Production :: when very high voltage of about 1000 volt is supplied between the anode and cathode then the electrons get deaccelerated when target the anode and the energy is released but only  one percent is x rays produced and rest heat is produced while the uv visible rays are produced by the high temperature source like sun .

Both are electromagnetic waves.

Absorption ::when the matter waves match with the x rays then these rays absorbed by the the the matter and cause the ionisation of electrons from the matter as these rays are high in energy and shorter in wavelength than uv visible rays while the uv visible rays cause the electronic transition of electrons from one level to another but these rays are also responsible for vibtation of molcule or atom because lower in energy than transition energy and then further cause rotation also for molecules or atoms because rotational energy further lower than vibrational energy.these three always occurs for uv visible light.
