So you see, light never really slows down - it just appears to because of the interactions that take place at the atomic scale.

The last three forces exist at the quantum level, which is the atomic scale.

Note that no surface is truly homogeneous, in the least at the atomic scale.

The composition of the human body can be viewed on an atomic and molecular scale as shown in this article.
