Question

Show analytically that an object between pole and focus of a concave mirror produces a virtual and enlarged image.

Answer 1

when an object is kept between pole and focus of a concave mirror, the image formed is behind the mirror, which means that it is not able to be caught on a screen, which makes it a virtual image, and is formed enlarged when we compare it with the size of the object.
example: a makeup mirror, the image obtained is always enlarged.
