Answer 2

When object is placed at:

Focus of concave mirror : The image is formed at infinity.

Radius of curvature : The image is formed between P and F.

Between pole and focus : The image is formed in Front of the mirror

Beyond center  of curvature : the image formed Between F and C

Explanation:

At F

Image formed is at infinity

Image formed is real and inverted and highly magnified .

At C

Image formed between P and F

Image formed is virtual and erect and magnified .

Between P and F

Image is in front of mirror .

Image formed is virtual erect and magnified .

Beyond C

Image formed is between F and C

Image formed is real and inverted and diminished .
