A double convex lens with a focal length of 45.0 cm is placed 65.0 cm from...
Suppose you have a double convex lens with a focal length of 15 cm and want to use it to form an image of an object 30 cm from the lens. How far behind the lens will the image form when it is "in focus", as sharply defined as possible? Give your answer in cm.15
2. An object is placed 26.0 cm in front of convex lens of focal length 45.0 cm. What is the magnification of the image?
15. (3 points) A convex lens of focal length of 20 cm is used to form an image of an object on a screen. (The setup is somewhat similar to what you used in the lab however it is not exactly the same.) The height of the object is 20 mm and the height of the image on the screen is 40 cm. (Note UNITS in the previous sentence!) How far from the lens must the screen be placed? Report...
An item is 20 em from a lens with a focal length of +12 em (convex lens). How far away must the screen be to produce a focused image, and what is the magnification of the image? Draw a rough picture of where the image is in relation to the object and the lens. 1. An item is 8 cm from a lens with a focal length of +12 cm (convex lens). Where does a focused image form? Can it...
An object is placed 6 cm from a convex lens of focal length 18 cm. what is the lateral magnification of the object.
6. A 4.00-cm tall light bulb is placed a distance of 45.7 cm from a double convex lens having a focal length of 15.2 cm. Determine the image distance and the image size. 7. A 4.00-cm tall light bulb is placed a distance of 8.30 cm from a double convex lens having a focal length of 15.2 cm. (NOTE: this is the same object and the same lens as in #6, only this time the object is placed closer to...
A) In the geometrical optics experiment, a student used a convex lens with 7 cm focal length to produce a large image of an object. The object was placed at a distance of 13 cm from the lens. Find the location of the formed image with respect to the lens (in cm). B) In the geometrical optics experiment, a student performed an experiment to measure the focal length of a convex lens. The object was placed at a distance of...
An object is placed 18 cm from the center of a converging lens of focal length 6 cm. 1) What will be the distance of the image from the lens? (cm) 2) What is the magnification of the image? 3) The object is moved. The image is now 10 cm away from the lens. How far is the object from the lens? (cm)
A convex lens has a focal length of 14.5 cm. Where on the lens axis should an object be placed in order to get a virtual, enlarged image with a magnification of 1.70? Answer in cm.
A 4.0 cm tall object is placed 8 cm in front of a double-convex lens (n = 1.52). The height of the image is y'- 7.0 cm. Based on this information find: a) The magnification, m. b) The image distance, s'. c) The focal length of this lens, f.
