Statement from passage: "Each f-value in the table is greater than the preceding one by a factor of √2, and this corresponds to a factor of 2 decrease in light intensity."
The question asked this: "Which of the following best describes the relationship between the f-stop value and the intensity of the light reaching the film?"
a) intensity is inversely-related to square root of f-value
b) intensity is inversely-related to square of f-value
Which one is it and how did you mathematically...
