A typical human eye is nearly spherical, and is usually about 2.5 cm in diameter. Suppose a person first looks at a coin that is 2.2 cm in diameter and located 26.0 cm from her eye. Then, she looks up at a friend who is 1.8 m tall and 3.00 m away. Find the approximate size of each image (coin ℎI,coin and friend ℎI,friend) on her retina. (Hint: Just consider rays from the top and bottom of the object that pass through the center of the lens.)

ℎI,coin= __cm
