Question

State the meaning of magnification in spherical mirrors. How is it related to object distance and image distance? When is magnification positive or negative?​

Answer 1

The magnification, m produced by a spherical mirror can be expressed as: m=h′h where h′ is height of image and h is height of object. ... And when the magnification is negative, that means image distance is negative or the image is formed in front of the mirror. So it is real.
