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 2.3 cm in diameter and located 30.5 cm from her eye. Then, she looks up at a friend who is 1.6 m tall and 3.50 m away. Find the approximate size of each image (coin ℎi_coin and friend ℎi_friend) on her retina. (Just consider rays from the top and bottom of the object that pass through the center of the lens)

ℎi_coin = __________ cm

ℎi_friend = __________ cm

The images on her retina are __________ (inverted or upright) and _________ (real or virtual)
