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 2.1 cm in diameter and located 29.0 cm from her eye. Then, she looks up at a friend who is 1.7 m tall and 4.00 m away. Find the approximate size of each image (coin hı,coin and friend hi,friend) on her retina. (Hint: Just consider rays from the top and bottom of the object that...

Your eye is 2.5cm in diameter. Which means that, for your eye, the image distance is fixed to 2.5cm. Your eye has a lens the shape of which your eye can change. What focal length must the lens of your eye have to see an object across Has 20, 8m away?

Constants Part A The maximum resolution of the eye depends on the diameter of the opening of the pupil (a diffraction effect) and the size of the light receptor cells (rods or cones) on the retina. The size of the retinal cells (about 5.0 am in diameter) limits the size of an object at the near point (25 em )of the eye to a height of about 50 pam. (To get a reasonable estimate without having to go through complicated...
