Chapter 34, Problem 68P
In Fig. 34-44, a real inverted image I of an object O is formed by a particular lens (not shown); the object – image separation is d = 40.0 cm, measured along the central axis of the lens. The image is just half the size of the object. (a) What kind of lens must be used to produce this image? (b) How far from the object must the lens be placed? (c) What is the focal length of the lens?

Two lenses (f1=100 mm, f2=-150 mm) are used to form an image of a candle on an observation screen. The distance between the lenses is kept small and is measured to be 3.5 cm. The distance of the candle from the center of both lenses is measured to be 82 cm. The distance of the image from the center of both lenses is measured to be 22 cm.
(i) What are the experimental focal length of the two combined lenses?
(a) 60 mm (b)1040 mm (c) 576.43 mm (d) 173.47 mm
(ii) What are the theoretical focal lengths of the two combined lenses?
(a) -50 mm (b) 176.47 mm (c) 280.37 mm (d) 52.63 mm
The smallest object we can resolve with our eye is limited by the size of the light receptor cells in the retina. In order for us to distinguish any detail in an object, its image cannot be any smaller than a single retinal cell. Although the size depends on the type of cell (rod or cone), a diameter of a few microns (μm) is typical near the center of the eye. We shall model the eye as a sphere 2.50 cm in diameter with a single thin lens at the front and the retina at the rear, with light receptor cells 5.0 μm in diameter. (a) What is the smallest object you can resolve at a near point of 25 cm? (b) What angle is subtended by this object at the eye? Express your answer in units of minutes (1°=60 min), and compare it with the typical experimental value of about 1.0 min. (Note: There are other limitations, such as the bending of light as it passes through the pupil, but we shall ignore them here.)
