Question

using a lens we can get a virtual image i. either smaller than object or ii.magnified
a. what kind of lenses are used for obtaining these images in both cases?
b. write the position of image formed in both situations
c. what should be the position of object in both situations?
d. show the ray diagram the image formation in both cases?​

Answer 1

Answer  Convex (converging) lenses can form either real or virtual images (cases 1 and 2, respectively), whereas concave (diverging) lenses can form only virtual images (always case 3). Real images are always inverted, but they can be either larger or smaller than the object.
