What is the main origin of electromagnetic waves?

Click For Summary
SUMMARY

The main origin of electromagnetic waves is derived from the behavior of wiggling charges, as explained through Maxwell's equations. By applying vector calculus to these equations, one can formulate a wave equation that describes both electric and magnetic field vectors. For those seeking a comprehensive introduction to this topic, "A Student's Guide To Maxwell's Equations" by Fleisch is highly recommended, as it covers the necessary vector calculus and the principles behind electromagnetic wave generation.

PREREQUISITES
  • Maxwell's Equations
  • Vector Calculus
  • Understanding of Electric and Magnetic Fields
  • Basic Wave Equation Concepts
NEXT STEPS

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.

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
