Unformatted text preview: x , we set dx/dp = 0 and solve for p . Since dx dp = p ( p − 2 f ) ( p − f ) 2 , the result is p = 2 f . The minimum distance is x min = p 2 p − f = (2 f ) 2 2 f − f = 4 f . This is a minimum, rather than a maximum, since the image distance i becomes large without bound as the object approaches the focal point....
