What is the effect of increasing exposure time on the x-ray?

  1. Increases quality

  2. Decreases quantity

  3. Increases quantity

  4. Decreases quality

The correct answer is: Increases quantity

Increasing exposure time on an X-ray will lead to an increase in the quantity of X-rays produced. This is because longer exposure times allow for more X-ray photons to be generated, resulting in a higher quantity of X-rays. This increased quantity can be beneficial when more detailed images are required to visualize structures or pathology. Therefore, the correct answer is that increasing exposure time on an X-ray increases the quantity of X-rays produced.
