Answer:
Explanation:
The spherical mirror can not be
convex because it does not form
real image (that can be formed on a screen).
So, the mirror has to be
conceal. In case of concave mirror,
the real image is formed if the
object distance greater than focal
length. For enlarged real image
the object should be placed
between the center and focus of
the mirror. The image formed
will be real, enlarged and inverted
so, the magnification will be -2.
