WebNov 20, 2024 · We use the magnification formula for a mirror to calculate the magnification or image size of an object. It is the following simple expression: m = - \frac {v} {u} m = −uv , where m m is linear magnification. Notice there is a minus sign which results from the … WebConcave mirrors, on the other hand, can have real images. If the object is further away from the mirror than the focal point, the image will be upside-down and real---meaning that the image appears on the same side of the mirror as the object. The closer the object comes to the focal point (without passing it), the bigger the image will be.
