Answer 1

Answer:

If magnification of a mirror is -1, we can assume many things:

1. The distance of object is similar to the distance of image.

2. Both v and u are negative.

3. The mirror has to be a concave mirror.

4. The object is placed on the centre of curvature and image is also formed there.

5. Image is real, inverted and as same size as object.
