When an object is at the centre of the curvature of a concave mirror, its image is formed at infinity.
Hence, the given statement is false.
The image formed by a concave mirror is real, inverted and highly diminished (much smaller than the object). The object must be : (a) between pole and focus (b) at focus (c) at the centre of curvature (d) at infinity
When an object is at infinity from a concave mirror, the image formed is
