# Transverse and longitudinal magnification

Contributor: Stas Fainer

This is a simulation of transverse and longitudinal magnification for an ideal lens with focal length $$f$$. The transverse (also called linear) and the longitudinal magnification is $$M_T=1-\frac{u}{f}$$ and $$M_L=\frac{dv}{du}$$ respectively, where $$u$$ and $$v$$ is the distance of the object and the image from our ideal lens, respectively. Also, for an ideal lens $$M_L=-(M_T)^2$$
