1.	The energy of characteristic X-ray is a consequence of which of the following?(a) The energy of the projectile electron(b) The thermal energy of the target(c) Transition in target atoms(d) TemperatureI had been asked this question in unit test.Origin of the question is Atomic Spectra in section Atoms of Physics – Class 12
Answer» CORRECT ANSWER is (c) Transition in target atoms Explanation: The energy of CHARACTERISTIC X-ray is a consequence of transition in target atoms. They cause EMISSION or absorption of electromagnetic RADIATION. The other options are not responsible for the energy of characteristic X rays.
