When target potential in the X-ray tube is increased

When the target potential in an X-ray tube is increased, the electrons that are accelerated towards the target will have higher kinetic energy. This means that they will collide with the target atoms with greater force, resulting in a higher frequency of X-ray photons being emitted from the target material.

The energy of an X-ray photon is directly proportional to its frequency, according to the equation E = hf, where E is the energy of the photon, h is Planck's constant, and f is the frequency of the photon. As the frequency of the emitted X-rays increases, so does their energy.

Therefore, increasing the target potential in an X-ray tube results in the production of X-rays with higher energies, which can be used for different imaging applications. However, increasing the potential also increases the risk of damaging the target material due to the increased energy of the electrons colliding with it. As such, there are limits to how high the potential can be set in an X-ray tube.
