The figure shows a boundary where the pulse changes direction, indicating a change in the optical density of the medium. The bending of the pulse is consistent with Snell's law, which states that when light travels from a medium of lower optical density to a medium of higher optical density, it refracts towards the normal. Therefore, the medium to the right of the boundary must be denser than the medium to the left.
