Surveying Question regarding EDM (Electromagnetic Distance Measure)
Q1) Is the
speed of light and radio waves
the same in a vacuum?
YES [my answer]
Q2) Is the
speed of light and radio waves
the same in the atmosphere?
YES [my answer]
With regards to Q2, I think that the SPEED is the same (C), but the velocity (which also involves a direction) would vary between the two just like different colours (Energy levels) of light refract differently when passing through the atmosphere. Their speed is the same as each other but the distance they traverse in a given space varies due to the refractive index of that
medium, and the atmosphere is a vast mixture. I think of a crystal prism spectragraph where you can see that the colours take different pathways.
Your thoughts would be appreciated. I need resolve so I can get some sleep
PS. If you know a good reference please include it.
