The image will be erect

The statement “The image will be formed at infinity” is NOT correct.
When an object is placed between the principal focus (F) and the pole (P) of a concave mirror, the reflected rays diverge but appear to originate from a point behind the mirror. This forms a virtual image.
For a concave mirror with an object between F and P:
– The image is formed behind the mirror.
– The image is virtual (cannot be projected on a screen).
– The image is erect (upright relative to the object).
– The image is magnified (larger than the object).
An image is formed at infinity by a concave mirror only when the object is placed exactly at the principal focus (F). When the object is between F and P, the image is virtual and located at a finite distance behind the mirror.
