A Question on Light and Temperature

[SGT]

Hmm - I will assume that 'c' is the speed of light?

So invisible light is also travelling at the same speed as visible light?

Faster?

Slower?

All electromagnetic radiation travels at the same speed in vacuum: radio waves, IR, visible light, UV, X-rays, gamma radiation.
Particles with zero rest mass, like neutrinos also travels at the same speed.

Okay so visible or invisible - their is a 'top speed' regarding motion and distance in this universe?

And all light, visible and invisible travels at the same speed, and all can be measured in vacuum?

So does lack of vacuum created variables in light speed?

If for lack of vacuum you mean existence of matter, yes! Light travels in air at a speed slightly less than in vacuum and in glass at a much lesser speed. This difference in speed when propagating in different media is what causes the phenomenon of refraction.

Now if we knew what "vacuum" actually is. Does a seething maelstrom of virtual-to-real, real-to-virtual particles, and particle/antiparticle pairs sound ok?
