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 uncorrected eye. For the following questions, assume that the distance between the eye lens and the retina is 1.70 cm. In other words, since the image is always formed on the retina, the distance between the lens and the image is always 1.70 cm. Also note that, as is seen in the ray diagram, since the eye lens is converging and the image is on the opposite side of the lens compared to the object, the image is always...

The crystalline lens of the human eye is a double-convex lens made of material having an index of refraction of 1.46. We shall assume that the radii of curvature of its two surfaces have the same magnitude. Assume the lens is embedded in a fluid having refractive index similar to air. If the radii of curvature of this lens is 7.82mm, what is its focal length? If an object 10.0 mm tall is placed 17.0 mm from the eye lens,...

Q2. Lenses and the Eye An object O is positioned 3.5 m from a lens of focal length f = -1.5 m as shown: Copy the diagram and draw in: the path of a parallel ray from the top of the object through the lens; the path of a ray through the centre of the lens; and hence the location of the image. Calculate the image distance di from the lens. Mark this distance on the diagram in a). A...

A lens with a focal length of 70 mm forms an image of a person on a digital image sensor. The person is standing 1.4 m away. 1. How far must the lens be from the image sensor in order for the image of the person to be in focus? 2. What kind of lens must it be to form the image: convex (converging) or concave (diverging)? Or could it be either kind?
