HEY THERE!
As we all know,
Light always travels at the speed of light.
But in a material it travels at the speed of light until it hits an atom. It is then absorbed and re-emitted in the same direction, which takes a small amount of time.
The more it happens, the slower the effective average speed.
The denser the material, the more atoms/elements there are in the way.
