If we place a point object at the focus of a concave mirror, we say that the reflected rays would be parallel and would meet at infinity to form an image.
What does this mean?
I tried to trace the reflected rays using the rules of image formation using a concave mirror and I got two rays almost parallel (negligible convergence). This could have been (and probably was) a construction error since achieving precision by hand is quite a difficult task to perform.
So, when we say that the reflected rays are parallel, do we mean that they are almost parallel and would meet at a lot of distance from the mirror? Is that also why we say that they will meet at infinity?
