A. You are looking at an object 1.75 m tall 30 m away from you. Assuming the eye is completely relaxed and that the nodal point of the eye is 1.65 cm in front of the retina, calculate the height of the image of the object on the retina, assuming that it is in focus. What is the focal length and the refractive power of the eye under these conditions?

B. You have shifted your focus to a nearby object 12 cm tall located a mere 0.6 m away. In doing so, your eye accommodates to bring its image into focus on the retina. What is the refractive power of the eye in this case? How tall is the image on the retina.

A. The human eye 1. Whenever a normal eye forms an image, the image distance will always equal the distance from the cornea and eye lens to the retina (~25 mm), regardless of how far away the object is located. Explain why the image distance cannot change. 2. If the image distance must change, then what intrinsic property of the eye lens must change in order for the eye to focus on objects at different distances? Hint: read the Introduction....

The physical properties of the relaxed eye are: distance from front surface of cornea to front surface of the lens: 3.6 mm, thickness of lens: 3.6 mm, cornea (r1): 8 mm, anterior surface of lens (r2):10.0 mm, posterior surface of lens (r3): 6.0 mm. The refractive index of aqueous and vitreous humor and lens are 1.34 and 1.41, respectively. With these properties, the distance from the cornea to the retina is 25 mm and an object infinitely far away is...

please be clear and radiate on how you solve this questions, I wish to learn from your guidance and help. thank you! The effective focal length of the cornea and the eye-lens can be considered as the focal length of an eye. The muscles controlling the curvature of the lens permit the eys to focus on the retina light from objects at different distances from the eye. When the eye muscles are relaxed the focal length of a healthy eye...

1) Two convex lenses, both with focal length 1.5 m, are placed such that the light from a 4 cm tall object passes through each. The object is placed 4.5 m from the first lens, and the lenses are 3 m apart. Where will the image from the first lens be? Will it be real or virtual? Will it be upright or inverted? Where will the final image be (using both lenses)? Will it be real or virtual? Upright or...
