Question

question 2 / 10
decreasing the source - to - image distance (sid) will result in which of the following?
increased production of photons
decreased concentration of photons
increased concentration of photons
decreased production of photons

Explanation:

The intensity of radiation (number of photons per unit area) follows the inverse - square law. When the source - to - image distance (SID) decreases, the same number of photons are spread over a smaller area, increasing the concentration of photons. The production of photons is related to the source characteristics and not directly to SID.

Answer:

Increased concentration of photons
