Lens Magnification Calculator

Formula

To calculate the magnification produced by a lens:

$M = \frac{v}{u}$

Where:

$M$ is the magnification
$v$ is the distance of the image formed by the lens
$u$ is the distance of the object from the lens

Magnification Definition

Magnification is the process of a lens refracting an image onto a surface and is defined as the ratio of the distance from the image to the distance from the object.

Example Calculation

Let's assume the following values:

Distance of the Image $v$ = 50 cm
Distance of the Object $u$ = 25 cm

Step 1: Divide the distance of the image by the distance of the object:

$M = \frac{50}{25} = 2$
