The mirror is a concave mirror.


The position of the object is in front of the mirror, while the position of the image is behind the mirror.


The nature of the image depends on the position of the object with respect to the mirror. In this case, since the magnification of the mirror is negative, it indicates that the image formed is virtual and upright.


When an object is placed in front of a concave mirror, the reflected rays converge at a point called the focal point. The distance between the focal point and the mirror is called the focal length. The position of the object and the distance of the object from the mirror affects the position and nature of the image formed.

In this case, since the magnification is negative, it indicates that the image formed is virtual, which means that the rays of light do not actually pass through the location of the image. The upright nature of the image indicates that it is a virtual image that is formed behind the mirror.

To determine the exact position of the image, we can use the mirror formula, which is given as:

1/f = 1/u + 1/v

where f is the focal length, u is the distance of the object from the mirror, and v is the distance of the image from the mirror.

Since the magnification is given as -1, we can use the magnification formula, which is given as:

m = -v/u

where m is the magnification.

By using these formulas, we can determine the exact position of the image formed by the concave mirror.
