Express your answer with the appropriate units. h = Submit μà Value Request Answer Units ?Minimum focal length of your eye Each of your eyes has a lens in it. This lens can change its shape and hence its focal length. By changing the focal length you are able to focus on an object based on how far away it is from you. For this problem you will determine the minimum focal length of your eye. A) Hold an object out in front of you at arm's length. Close one eye and bring the object towards your eye and determine how close it can be to your eye and still be in focus. 25 cm ✓ B.) The average human eye has an image distance of 1.7 cm. In other words, it is 1.7 cm from the lens in your eye to the retina. Using this information and your answer to (A), determine the minimum focal length of your eye. Also determine the magnification for this situation. min 6 x Units are required for this answer. M = 8 X C.) The lens in your eye creates an image. It is this image that the rods and cones in our eye actually detect. Regarding the image your lens created when finding the minimum focal…

You are designing an endoscope for use inside an air-filled body cavity. The figure shows the end of the scope that will be inside the body. Viewing bundle Object Objective lens mm An objective lens will form an image that covers the entire area of the end of a viewing bundle of optical fibers. The radius of the bundle and, therefore, the image of the lens, is r = 1.00 mm. This image will then be carried by the optical fibers to an eyepiece lens at the outside end of the fiberscope, not shown in the figure. The tissues you wish to observe ("Object" in the figure) that are to appear within the image fill a circle of radius r 5.30 cm. The lens will be located a distance p = 4.77 cm from the object.
