SOLUTION: F-stop and aperture diamter the relative aperture or f-stop for a camera lens is inversely proportional to the diameter of the aperture an f-stop of 2.8 corresponds to an aperture

Question 1134797: F-stop and aperture diamter
the relative aperture or f-stop for a camera lens is inversely proportional to the diameter of the aperture an f-stop of 2.8 corresponds to an aperture diameter of 75 millimeters for a certain telephoto lens
a.find the equation that relates f-stop and diameter
b.graph the equation from part a. in the first quadrant only
c. what aperture diameter correspnds to an f-stop of 5.6
