A concave lens has a focal length of -36 cm. Find the image distance and magnification that results when an object is placed 19 cm in front of the lens. (Use the proper sign convention for both quantities.) When an object is located 61 cm to the left of a lens, the image is formed 25 cm to the right of the lens. What is the focal length of the lens? An object with a height of 2.22 cm is...
4. (20 pts) A simple digital camera lens with a focal length 4.00 cm forms a sharp image of an object on a sensor screen located 14.0 cm from the lens. The object now moves away from the lens and the new distance required between the lens and sensor is 13.0 cm. a. Find the original distance from the lens to the object. b. By what amount did the object change its distance from the lens? c. Find the original...

A lens for a 35-mm camera has a focal length given by f = 50.5 mm . How close to the CCD sensor should the lens be placed to form a sharp image of an object that is 5.20 m away?
You have a camera with a fixed lens-to-film distance = 6.0 cm. What focal length lens is needed to take a picture of an object located 4.0 m in front of the camera lens?
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...
