Question: The energy of a photon of characteristic X-rays from a Coolidge tube comes from [MP PET 1995]
Options:
A) The kinetic energy of the striking electron
B) The kinetic energy of the free electrons of the target
C) The kinetic energy of the ions of the target
D) An electronic transition of the target atom
Show Answer
Answer:
Correct Answer: D
Solution:
The energy of X-ray photon obtained from a coolidge tube by an electronic transition of target atom such as $ {K_{\alpha }} $ line is obtained from transition from L orbit in K orbit.
