Increasing kVp has what effect on image contrast and penetration?

Explanation:
Increasing kVp raises the energy of the X-ray photons, so the beam becomes more penetrating. At the same time, higher energy photons are less attenuated differently by tissues, which reduces the difference in brightness between structures and thus lowers image contrast. Because you gain penetration but lose contrast, there’s a trade-off: you may need to adjust other factors (like exposure) to keep the image diagnostic. That’s why the correct statement notes both the decrease in contrast and the increase in penetration, with a reminder that beam energy rises requiring balance.
