What is the effect of increasing the voltage across an X-ray tube on the X-ray beam intensity?.
- A.Decreases intensity
- B.Increases intensity
- C.No effect on intensity
- D.Increases wavelength
Model answer
What a good answer should say
- Increases intensity
Explanation
Why this works
Increasing the voltage increases the energy of the electrons, leading to more energetic X-ray photons being produced, which increases the overall intensity of the X-ray beam.
