SUMMARY
Photons can be slowed down when they travel through mediums such as air and water due to interactions with the atoms in these materials, which results in a reduced effective speed. However, the fundamental speed of light in a vacuum remains constant at approximately 299,792 kilometers per second, as dictated by special relativity. Observers in different frames of reference will always measure the speed of light in a vacuum as the same, regardless of the medium through which photons travel. This discussion clarifies that while photons can be delayed in mediums, they cannot be caught by a "lightspeed rocket" because their intrinsic speed remains unchanged.
