Question

increasing the energy of an incident electron will result in the production of an x - ray photon with greater energy. less energy. greater charge. greater velocity. 18 multiple choice 1 point if kvp is doubled, the amount of x - ray photons created approximately increases twofold. threefold. fourfold. eightfold.

Explanation:

1. For the first question, the energy of an x - ray photon is directly related to the energy of the incident electron. Higher - energy incident electrons result in x - ray photons with greater energy. Photons are chargeless and their speed in a vacuum is the speed of light (constant), so charge and velocity are not affected.
2. For the second question, the number of x - ray photons created is approximately proportional to the square of the kilovoltage (kVp). When kVp is doubled, the number of photons increases by a factor of 4 (since $2^2=4$).

Answer:

1. greater energy
2. fourfold
