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.
