For real image magnification is negative or positive

Magnification is the measure of how much larger or smaller an image is in comparison to the actual object. It represents the ratio of the size of the image to the size of the object.

A real image is an image that is formed when the rays of light actually converge at a point after reflection or refraction. We can not project a real image onto a screen. The real image is always inverted.

The formula for Magnification:

M = \frac{Height of Image h'}{Height of object h} = \frac{-v}{u}\frac{Height of Image h'}{Height of object h} = \frac{-v}{u}

V = Image distance

U = Object distance

Since real images are always inverted, the magnification will be negative.
