What is the main origin of electromagnetic waves?

Click For Summary

Discussion Overview

The discussion centers around the origin of electromagnetic waves, exploring the fundamental causes and mechanisms behind their generation. Participants delve into theoretical aspects, particularly referencing Maxwell's equations and the role of charges in the formation of electromagnetic waves.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification

Main Points Raised

  • Some participants suggest that electromagnetic waves originate from wiggling charges.
  • Others reference Maxwell's equations as a foundational framework for deriving the wave equation for electric and magnetic fields.
  • One participant expresses a need for clarification on the generation of electromagnetic waves, indicating a misunderstanding in their initial question.
  • There are suggestions for resources, such as "A Student's Guide To Maxwell's Equations," to aid in understanding the topic.

Areas of Agreement / Disagreement

Participants present multiple viewpoints regarding the origin of electromagnetic waves, with no consensus reached on a singular explanation. The discussion remains unresolved as participants clarify their questions and responses.

Contextual Notes

Some participants express uncertainty in their phrasing and understanding, which may affect the clarity of the discussion. There are indications of missing assumptions regarding the definitions and context of electromagnetic wave generation.

When applying maxwells equations to the wave equation, or unless i have misunderstood your question.
 
Using some fairly basic vector calculus, one can derive a wave equation for both the magnetic and electric field vectors from Maxwell's equations.

If you want a straightforward introduction to Maxwell's equations that covers up to electromagnetic waves, I suggest "A Student's Guide To Maxwell's Equations" by Fleisch - this introduces vector calculus too.
 
Wiggling charges.

I don't intend this

sorry I mistake in using expressions in my question!

excuse my because I am not good in speaking english

my question in other form

from what generate the electromagnetic waves?

or how we obtain the electromagnetic waves?

or what is the cause behind existence the electromagnetic waves?

thanks a lot

but; excuse me; can you demonstrate this point in details ??

thanks a lot

but I think that I mistake in writing my question

can you read my reply number 5 in this topic to know what I intend
