UV radiations and X - rays are:
UV radiations are produced by the high energy transitions of the electrons in atoms. UV radiations have wavelengths ranging from 0.4 m m to 1nm. X - rays are produced in discrete wavelengths in individual transitions among the inner electrons of an atom.
When decelerated electrons are scattered to the target in coulidge tube equipment X - rays are produced.
X - rays are used in medical diagnosis called "Radiography". X - rays are used to cure the diseases the is called "Radiotherapy". X - rays are emitted in radio activity.
