      Question

      Which change would directly cause the minimum

      wavelength in X-ray emission to decrease?
      A Increasing the accelerating potential Correct Answer Incorrect Answer
      B Increasing the filament current Correct Answer Incorrect Answer
      C Decreasing the pressure in the tube Correct Answer Incorrect Answer
      D Replacing the target metal with one of higher atomic number Correct Answer Incorrect Answer

      Solution

      The minimum wavelength in X-ray emission corresponds to the maximum energy of emitted X-rays, which depends directly on the kinetic energy of the incident electrons . This kinetic energy is determined by the accelerating potential (V) applied across the X-ray tube. The relation is: So, increasing the accelerating potential increases the maximum energy, thereby decreasing the minimum wavelength of emitted X-rays.
