Kilovoltage determines the what of the x-ray beam?

Explanation:
Kilovoltage sets the energy of the X-ray photons. When kVp is higher, the photons have more energy and can pass through tissues more readily, increasing the beam’s penetrating quality. That direct link—higher energy equals greater penetration—is why kilovoltage is described as determining the beam’s penetrating quality. Density is mainly about how many photons are produced (mA and exposure time), and wavelength is a physical property tied to energy but not the usual term used to describe the clinical effect of kVp; the practical takeaway is the beam’s penetrating capability.
