- TL;DR Summary
- Light is travelling as a photon, what extent is change in journey distance affecting wavelength
given it's only at one place at a time? Also, a reduction in frequency is a reduction in energy, so how and where is that energy gone?
On a long trip the photon goes, but it occupies a wavelength of space at any particular time. If the space between start and finish (inspection) is expanding all the way all the journey time, then most of the expansion has no effect on the photon. Like eg second tenth is section currently passed thru, but the effect takes place on the other say ninety percent all the total time period. So, did I get that right? Also, the photon lost energy by reducing it's frequency but where went the energy? And, in the vicinity of that proton within a wavelength, does space expand? Last, why does light travel below c in a medium? Is it curving next to atoms because space is not empty?
