Final answer:
X-rays are produced from transitions between inner-shell electron levels or by decelerating electrons. However, the main sources of X-rays are: Electron clouds: X-rays are produced when high-energy electrons strike a target material, Electron clouds and atomic nucleus are both sources of X-rays.
Step-by-step explanation:
X-rays are produced from transitions between inner-shell electron levels or by decelerating electrons. However, the main sources of X-rays are: Electron clouds: X-rays are produced when high-energy electrons strike a target material, such as the anode in an X-ray tube. Atomic nucleus: X-ray photons can also be emitted as a result of nuclear interactions, such as radioactive decay. Based on this information, the correct answer is option 3) both electron clouds and atomic nucleus are sources of X-rays.
