People who do very detailed work close up, such as jewelers, often can see objects clearly at a much closer distance than the normal 25.0cm. What is the power of the eyes of a woman who can see an object clearly at a distance of only 8.75cm? Assume a distance from the eye lens to the retina of 2.00cm

power: 61.43diopters -right

What is the size of the image of a 1.50mm object, such as lettering inside a ring, held at this distance? Enter your answer as a positive number if the image is upright and negative if it is inverted.

image size at : −0.23- wrong

What would the size of the image be if the object were held at the normal 25.0cm ?

image size at : −0.34 - wrong
