Assertion : When an electron beam strikes the target in an X-ray tube, part of the kinetic energy is converted into X-ray energy. Reason : If the accelerating potential in an X -ray tube is increased, the wavelengths of the characteristic X-rays do not change.

Options

  1. AIf both assertion and reason are true and reason is the correct explanation of assertion.
  2. BIf both assertion and reason are true but reason is not the correct explanation of assertion.
  3. CIf assertion is true but reason is false.
  4. DIf both assertion and reason are false.
