WebMay 26, 2024 · where f is the focal length. u is the object’s distance from the lens. v is the image distance from the lens. Magnification of Lens Magnification refers to enlarging something, it means that the object itself doesn’t become physically larger but only larger in its appearance. WebTo obtain this type of numerical information, it is necessary to use the Mirror Equation and the Magnification Equation. The mirror equation expresses the quantitative relationship between the object distance (do), the image distance (di), and the focal length (f). The equation is stated as follows: 1/f = 1/di + 1/do
