Question

When the object is formed at 2f1 of a convex lens what is the position of image

Answer 1

Answer:

the image will not be formed

Explanation:

whenever object is at 2f1/f1 the image will not be formed because the rays after converging/refracting from the lens will not meet (or more precisely meet at infinitely large distance, that we practically don't know) , so it doesn't form an real image but we can say that it forms a virtual(more appropriate). Though in some textbooks, its mostly given as (image not formed). But we can also say that it forms a virtual image.
