Ibn_Sahl.svg‎ (SVG file, nominally 610 × 449 pixels, file size: 8 KB)

[edit] Summary

I drew this, based on a description and similar figure in Geometric Optics on Phase Space By Kurt Bernardo Wolf.[1]

If the ratio L1/L2 is equal to the ratio of indices of refraction n1/n2, then the figure is a representation of Snell's law, in a form intended to explain Ibn Sahl's derivation.
