Answer: A convex mirror always forms an erect image. So, it cannot be a convex mirror.
As the linear magnification = -1/3
1) The type of mirror is a concave mirror.
2) When the object is placed beyond the center of curvature, the image formed is between the focus and center of curvature.
The Ray Diagram is shown in the picture -
It is clearly visible that -
AB is the object.
C``D`` is the diminished and inverted image.
So, the linear magnification of the image is -1/3.
The - sign indicates an inverted image.
A value less than 1 indicates a diminished image.
