Question

If magnification is -1 which type of mirror and nature of image

Answer 1

Answer:

However, if an image is behind the mirror, the situation is different. In any case, a convex mirror will have a negative focal length. Virtual images will be located behind the mirror surface. Negative magnification means that the image formed by a spherical mirror is real and inverted.

Explanation:

Magnification: The ratio of the height of the image to the height of the object is called the magnification of the spherical mirror. The magnification of the actual image will always be negative and the virtual image should always be positive
