For safety reasons, you install a rear-window lens with a -0.296 m focal length in your van. Before putting the van in reverse, you look through the lens and see the image of a person who appears to be 0.341 m tall and 0.235 m behind the van. Determine the following. (a) distance of the person behind the van -1.14 Can you write the thin lens equation which gives a relationship between the focal length of a lens, the object...
The owner of a van installs a rear-window lens that has a focal length of -0.320 m. When the owner looks out through the lens at an object located directly behind the van, the object appears to be 0.200 m from the back of the van, and appears to be 0.310 m tall. (a) How far from the van is the object actually located, and (b) how tall is the object?
Chapter 26, Problem 05o The owner of a van installs a rear-window lens that has a focal length of-0.350 m. When the owner looks out through the lens at an object located directly behind the van the object appears to be 0.230 m from the back of the van, and appears to be 0.360 m tall. (a) How far from the van is the object actually located, and (b) how tall is the object? Rear-window len Person mage of person
Q 15: A camera with a 7.0-cm focal length lens is used to photograph a person who is 2.0 m tall. The height of the image on the film must be no greater than 7.0 cm. Calculate the closest distance the person can stand to the lens. Q 19: A man who can produce sharp images on his retina only of objects that lie from 55 cm to 290 cm from his eyes needs bifocal lenses. Determine the desired focal...
A movie camera with a (single) lens of focal length 51.6 mm takes a picture of a person standing 31.9 m away. If the person is 138.5 cm tall, what is the height of the image on the film?
A movie camera with a (single) lens of focal length 61 mm takes a picture of a person standing 27 m away. If the person is 181 cm tall, what is the height of the image of the person on the film? mm
A movie camera with a (single) lens of focal length 110 mm takes a picture of a person standing 36 m away. If the person is 180 cm tall, what is the height of the image in millimeters on the film?
A movie camera with a (single) lens of focal length 70 mm takes a picture of a person standing 31 m away. If the person is 160 cm tall, what is the height of the image in millimeters on the film?
A 5 cm tall object stands in front of a converging lens with focal length f = 35 cm. The distance between the object and the lens is 10 cm. (a) Give the power of the lens. (b) Calculate the position and height of the image formed. Is the image real or virtual? (c) In the space below clearly produce the ray diagram (at least two of the three rays that form the image). A farsighted person uses spectacles formed...
Giving an optical system compose of two lens system. Lens 1 focal length = 10-cm, Lens 2 focal length = 5-cm. The distance between the two lenses L = 50-cm. An object is 30 meter away from Lens 1, with height of 10-cm (a) Setup the equation, that solve the image location and the magnification, at each lens? (b) Solve the image location, magnification, and height at each lens? (c) If you want the object to have a final magnification...
