A convex, or converging, lens with a focal length of 34 cm is used to observe an image of an apple than is 80 cm away from the lens.

Part A

A convex, or converging, lens with a focal length of 34 cm is used to observe an image of an apple than is 80 cm away from the lens. At what

distance from the lens does the image form and what type of image is it?

46 cm, virtual

46 cm, real

59 cm, real

59 cm, virtual

24 cm, real

24 cm, virtual

Part B

A person's eye has a diameter of 2.5 cm and a converging lens that produces a clear, real image on the retina. When viewing an apple, the eye's lens has a focal length of 2.4 cm. What is the distance between the apple and the person's eyes?

1.2 cm

0.017 cm

0.10 cm

60 cm

Part C

A nearsighted person wants to see an apple that is 7 meters away but can only clearly see objects that are at most 62 cm away from her eyes. Eyeglasses made of diverging corrective lenses can help her to see the apple clearly. If her glasses are 2.5 cm in front of her eyes, what should be the power of these corrective lenses to allow her to see the apple?

-1.47 diopters

-1.54 diopters

+21 diopters

-65 diopters
