consider a concave mirror with a focal length of 13.72cm, and the object distance is 6.86cm, i calculated and found the image distance to be -13.72cm and a magnification of 2
how would i describe the image.
1. virtual, inverted, larger
2. none of these
3. real, upright, smaller,
4. real, upright, larger
