Homework Statement
An object is placed against the center of a spherical mirror and then moved 79 cm from it along the central axis as the image distance i is measured. Figure 34-35 gives i versus object distance p out to ps = 45 cm. What is the image distance when the object is on the central axis and 79 cm from the mirror?
The image distance is the y-axis from -400 to 400cm. The object distance is from 0 to ps on the x-axis. The graph looks like a graph of the function 1/x.
Homework Equations
1/f=1/p+1/i
The Attempt at a Solution
1/22.5=1/79+1/i
i= +31.5cm
Is my answer correct?
