a. The power of making an image larger
Magnification is the ratio of the image size to the object size. Magnification (M) = height of the image / height of the object. When the ratio is greater than one we say the image is magnified and when less than one we say it is diminished.
Also magnification = image distance from the mirror / object distance from the mirror.
