Propagation of electromagnetic wave

Click For Summary

Discussion Overview

The discussion centers around whether the distance traveled by electromagnetic (EM) waves is influenced by temperature, exploring the relationship between temperature, medium properties, and wave propagation. The scope includes theoretical considerations and conceptual clarifications regarding EM waves, particularly in different media.

Discussion Character

  • Exploratory, Conceptual clarification, Technical explanation

Main Points Raised

  • One participant questions if the distance traveled by an EM wave depends on temperature and requests an explanation.
  • Another participant asks for clarification on what is meant by "medium" in the context of EM wave propagation.
  • A participant identifies EM waves specifically as radio waves.
  • It is proposed that the speed of EM waves is constant in a vacuum but varies in different media due to their permittivity and refractive index, which are temperature-dependent. This implies that if the speed changes, the distance traveled in a given time would also change.
  • A participant clarifies that "medium" refers to "material."

Areas of Agreement / Disagreement

Participants express varying levels of understanding regarding the influence of temperature on EM wave propagation, with some proposing that it does affect the distance traveled while others seek clarification on terminology and concepts. No consensus is reached on the initial question.

Contextual Notes

The discussion does not resolve the assumptions regarding the specific conditions under which temperature might affect wave propagation, nor does it clarify the implications of different media on EM wave behavior.

will the distance traveled by an em wave depends on temperature,if so then explain
 
Physics news on Phys.org
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".
