The eye can be treated as a spherical optical surface filled with a fluid with an index of refraction of 1.34. An object with a height 9.50 cm is placed 44.5 cm from the front of the eye. A clear image forms on the retina at the back of the eye with an image height of -3.55 mm. What is the diameter of the eye? Give your answer in cm to 2 decimal places but do NOT include units with your answer.

- 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 2.4 cm in diameter and located 34.0 cm from her eye. Then, she looks up at a friend who is 1.8 m tall and 4.00 m away. Find the magnitude of 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.) b) Are the images on her retina upright/inverted and/or virtual/real?A ray of light strikes a flat block of glass at an incidence angle of ?1 = 38.6°. The glass is 2.00 cm thick and has an index of refraction that equals ng = 1.52. (a) What is the angle of refraction, ?2,that describes the light ray after it enters the glass from above? (Enter your answer in degrees to at least 2 decimal places.) b.)With what angle of incidence, ?3,does the ray approach the interface at the bottom of the glass? (Enter your answer in degrees to at least 2 decimal places.)A far-sighted patient has contacts' prescription for +3.00 D, and this prescription gives her a perfect vision. What is her near point?
