Nettet12. sep. 2024 · This situation is similar to that shown in Figure \(\PageIndex{1}\). To find the overall magnification, we must know the linear magnification of the objective and … Nettetif that's true, then convex lenses would make objects smaller, which is not the case. – AccidentalFourierTransform.

(a) The linear magnification of a concave lens is always
Some optical instruments provide visual aid by magnifying small or distant subjects. • A magnifying glass, which uses a positive (convex) lens to make things look bigger by allowing the user to hold them closer to their eye. • A telescope, which uses its large objective lens or primary mirror to create an image of a distant object and then allows the user to examine the image closely with a smaller eyepiece lens, thus making the object look larger. Nettet(a) The magnification is positive for all virtual images and is negative for all real images. (b) The magnification of concave lens and convex mirror is always positive where as … NettetThat's why it gave you this distance between lenses. The distance between lenses is 33 centimeters. So if the distance from this 1st lens is 18 well the difference has to be equal to this length. So 33 minus 18 is … jコム 光回線
