A)The cutoff wavelength depends on the target material.
B)The cutoff wavelength depends on the potential difference across the X-ray tube.
C)The cutoff wavelength is independent of the energy of the incident electrons.
D)The cutoff wavelength occurs because of the mutual shielding effects of K-shell electrons.
E)The cutoff wavelength occurs because an incident electron cannot give up all of its energy.
