State whether the image will move closer to or farther away from the focus as the object is moved away from the mirror? Figure . Figure . Figure . Figure . Figure . Formation of image by a convex mirror You have so far studied the image formation by a plane mirror, a concave mirror and a convex mirror. Which of these mirrors will give the full image of a large object? Let us explore through an Activity.
