Chapter 35, Problem 42P
Astronomers often take photographs with the objective lens or mirror of a telescope alone, without an eyepiece. (a) Show that the image size h′ for such a telescope is given by h′ = fh/(f − p), where f is the objective focal length, h is the object size, and p is the object distance. (b) What If? Simplify the expression in part (a) for the case in which the object distance is much greater than objective focal length. (c) The “wingspan” of the International Space Station is 108.6 m, the overall width of its solar panel configuration. When the station is orbiting at an altitude of 407 km, find the width of the image formed by a telescope objective of focal length 4.00 m.

A measurement indicates that a patient cannot clearly see any object that lies closer than 75.0 cm to the patient's eye.(a) Which of the terms [focal length, far point, magnification, near point]best describes this distance?(b) The patient needs to be able to clearly see objects that are just 23.0 cm distant. A contact lens is called for. What focal length should this lens have? Assume the lens can be modeled as an ideal thin lens, which lies adjacent to the eye.(c) What is the power, P, of the contact lens (in diopters)?
A wire mesh consists of squares each of side 1 mm.
It is placed at a distance of 9.0 cm from a magnifying
glass of focal length 10 cm. It is viewed by placing
the eye close to the lens. (a) What is the magnification
produced by the lens? (b) What is the area of each
square in the virtual image of the mesh? (c) What is the
magnifying power of the lens? (d) Is the magnification
(a) equal to the magnifying power in (c)? If not, when
can they be made equal to each other? Explain.
When two lenses are used in combination, the first one forms an image that then serves as the object for the second lens. The magnification of the combination is the ratio of the height of the final image to the height of the object. This is equal to the product of the separate magnification values mm of each lens. In equation form
mtotal=(m1)(m2).
A 1.20 cm tall object is 50.0 cm to the left of a lens of focal length of magnitude 40.0 cm . A second lens, this one having a focal length of magnitude 60.0 cm, is located 300 cm to the right of the first lens along the same optic axis.
A)
Find the location and height of the image (call it I2) formed by the lens with a focal length of 40.0 cm if the first lens is diverging and the second lens is a converging.
B)
I2 is now the object for the second lens. Find the location and height of the image produced by the second lens.
