Propagation of electromagnetic wave

[jeevansai]

Main Question or Discussion Point

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

 

[Drakkith]

What medium is the EM wave traveling through?

 

[jeevansai]

what does it mean can you elaborate please

 

[jeevansai]

the em waves are radio waves

 

[ehild]

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 travelled in the same time is also different.

The word "medium" means "material".
