Explanation:
Detailed explanation-1: -Use the lens equation to get di. If you know the distance of the object you’re magnifying from the lens and the focal length of the lens, finding the distance of the image is easy with the lens equation. The lens equation is 1/f = 1/do + 1/di, where f = the focal length of the lens.
Detailed explanation-2: -Magnification equation Magnification = image size / actual size. Actual size = image size / magnification.
Detailed explanation-3: -Let’s explore the magnification formula (M= v/u) for lenses and see how to find the image height and its nature (whether it’s real or virtual).
Detailed explanation-4: -Solution: If the magnification of a body of size 1 m is +2, then the size of the image is 2 m.
