To calculate the magnification produced by a lens:
\[ M = \frac{v}{u} \]
Where:
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.
Let's assume the following values:
Step 1: Divide the distance of the image by the distance of the object:
\[ M = \frac{50}{25} = 2 \]
