Final answer:
As the percentage of photoelectric interactions increases, the overall x-ray intensity decreases.
Step-by-step explanation:
As the percentage of photoelectric interactions increases, the overall x-ray intensity decreases. Photoelectric interactions refer to the process where an incoming x-ray photon transfers all its energy to an atom, ejecting an electron. As the number of photoelectric interactions increases, more x-ray photons are absorbed, resulting in a decrease in the overall x-ray intensity. The energy and wavelength of the x-rays remain unchanged in this process.
