Are there nonliquid materials in which we can observe subsurface scattering (as in the picture on the bottom right). I usually only see it mentioned with regard to rendering accurate water but was curious how prevalent of an effect it is in real life light physics.

As mentioned in lecture, light "bends" when entering a new medium, from one density to another, such as the case of moving from air to water. How light refracts depends on the relationship between materials, and the orientation of the surface where they meet.
