Hi,
What is people measuring when they measure the speed of light (c) actually? the photons or the waves? or some kind of manifestation of light?
I ask because I was reading about photons and that they "might" have a very small mass and therefore are not traveling at c. If photons have a mass, and are traveling slower than c what exactly is being measured when they measure the speed of light?
Thanks
