. A person looks at a statue that is 2 m tall. The image on the persons retina is inverted and 0.005 m high. What is the magnification?
Two convex lenses of focal lengths 20 cm and 10 cm are placed 30 cm apart, with the lens with the longer focal length on the right. An object of height 2.0 cm is placed midway between them and observed through each lens from the left and from the right. Describe what you will see, such as where the image(s) will appear, whether they will be upright or inverted and their magnifications.
What are the differences between real and virtual images? How can you tell (by looking) whether an image formed by a single lens or mirror is real or virtual?
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.
Objects viewed through a microscope are placed very close to the focal point of the objective lens. Show that the minimum separation x of two objects resolvable through the microscope is given by x=1.22f0D , where f0is the focal length and D is the diameter of the objective lens as shown below.
A diverging lens has a focal length of 20 cm. What is the power of the lens in diopters?
Suppose a 200 mm focal length telephoto lens is being used to photograph mountains 10.0 km away. (a) Where is file image? (b) What is the height of the image of a 1000 m high cliff on one of the mountains?
A magnifying glass forms an image 10 cm on the opposite side of the lens from the object, which is 10 cm away. What is the magnification of this lens for a person with a normal near point if their eye 12 cm from the object?
. (a) In a camera equipped with a 50-mm focal-length lens, the maximum distance that the lens can be from the film is 60 mm. What is the smallest distance an object can be from the camera if its image on the film is to be in focus? What is the magnification? (b) An extension tube is added between the lens and the camera body so that the lens can be positioned 100 mm from film. How close can the object be now? What is the magnification?
The shell” of a concept map dealing with lenses and their properties is shown in Concept Map 9.2. Most of the concepts and all of the linking phrases needed to form meaningful propositions have been left out. Complete this map by selecting the appropriate concepts and linkages from the lists that follow. Some connecting words will have to be used more than once to finish the map correctly. If you need to, be sure to review Sections 9.3 through 9.5 for help in properly determining and relating the relevant concepts.
(a) The print in many books averages 3.50 mm in height. How high is the image at the print on the retina when the book is held 30.0 cm from the eye? (b) Compare the size of the print to the sizes of rods and cones in the fovea and discuss the possible details observable in the letters. (The eye-brain system can perform better because of interconnections and higher order image processing.)
