Find the position and size of the image. click for answer Your IP: 192.169.198.130 Magnification produced by a lens is also related to the object-distance u, and the image-distance v and is given by Focal length, f = +10 cm (convex lens); Therefore, the image is real, inverted, 30 cm from the lens, on the opposite side of the object and magnified 2 times. Spherical Lens. Lenses, both converging and diverging, are the marvels of optical physics that use the ability of these media to refract, reflect, or bend light rays. A 6 cm object is placed perpendicular to the principal axis of a convex lens of focal length 15 cm. The sign for distance is given as per convention. all rights reserved. At what distance should the object from the lens be placed so that it forms an image at 10 cm from the lens? Revise with Concepts. • Copyright © 2020 Entrancei. Revise with Concepts. Overview. 3 min.
