Propagation of electromagnetic wave

Click For Summary
The distance traveled by an electromagnetic (EM) wave, such as radio waves, is influenced by the temperature of the medium through which it travels. EM waves propagate at the speed of light, which is constant in a vacuum but varies in different materials based on their permittivity and refractive index. These material properties are temperature-dependent, affecting the speed of light in that medium. Consequently, if the speed of light changes due to temperature variations, the distance the wave can travel in a given time will also change. Understanding the relationship between temperature, medium properties, and wave propagation is crucial for applications in telecommunications and physics.

will the distance traveled by an em wave depends on temperature,if so then explain

What medium is the EM wave traveling through?
 
what does it mean can you elaborate please
 
the em waves are radio waves
 
The EM waves travel with the speed of light.You know it is c in vacuum, but different from c in media, having different permittivity / refractive index. These material properties depend on the temperature, so the speed of light in a medium also depends on the temperature. If the speed is different, the distance traveled in the same time is also different.
 
The word "medium" means "material".

Thread 'Colors in a plasma globe'

I have a common plasma globe with blue streamers and orange pads at both ends. The orange light is emitted by neon and the blue light is presumably emitted by argon and xenon. Why are the streamers blue while the pads at both ends are orange? A plasma globe's electric field is strong near the central electrode, decreasing with distance, so I would not expect the orange color at both ends.
