Linear magnification produced by a convex lens can be : (a) less than 1 or more than 1 (b) less than 1 or equal to 1 (c) more than 1 or equal to 1 (d) less than 1, equal to 1 or more than 1
Depending on the position of the object, a convex lens can produce either smaller, same size or larger image. So the value of magnification can be less than 1, equal to 1 or greater than 1 and the correct choice is (d).
