ekambaram is doing an experiment using mirrors to understand the concept of magnification is found to be greater than
1)what type of mirror he used for experiment?
2)what is the type of the object for the above situation?

Answer 1

1.  If the magnification is greater than 1 (m < -1) ,  the concave mirror is used for the experiment.

 A real object is placed between the focus and center of curvature. It forms an inverted real image.

 =====================================

If the real object is kept with in the focus of the concave mirror, then a virtual image is formed.
In this case also the magnification is more than 1. (m > +1)
