Question

if object lies at large distance from a convex lens where is the image formed​

Answer 1

Answer:

At a point between the focus and the lens. because all the rays from various points on the object try to converge at the focus

Explanation:

So height and width of image at focal length from lens is zero. But at a place between lens and focus we get a clear image. This rule we use in a pin hole camera where the pin hole serves the purpose of a lens.
