> photons get slowed down when traveling through a medium

no

They sometimes still teach you this in schools, but it is not true. Light is always light-speed fast.

You think it takes a longer time through a medium because it interacts with the atoms inside of it (absorption, emission etc.). When a photon is absorbed, it takes some time for it to get emitted again, that's why there's time missing.

Between these interactions it is still traveling at the speed of light.
