C)decreasing x-ray wavelength.
D)photon energies above 1.02 mMeV.

Question

Quizplus · Accepted Answer

The photoelectric effect occurs when an incoming photon is absorbed by an atom and ejects an electron out of the atom. This process is more likely to occur with atoms that have a higher atomic number because they have more tightly bound electrons closer to the nucleus, making them more likely to be struck by the photon. Kilovoltage and x-ray wavelength are not directly related to the incidence of the photoelectric effect, while photon energies above 1.02 mMeV are more likely to result in pair production rather than the photoelectric effect.
