Electromagnetic waves are chargeless?

Click For Summary
SUMMARY

Electromagnetic (EM) waves are generated by accelerated charges, yet they themselves are chargeless entities. The discussion clarifies that while EM waves consist of electric and magnetic fields, the charge is merely the source of these waves. Once the EM wave propagates, it does not retain any charge, similar to how sound waves, produced by vocal cords, do not carry vocal cords with them. This distinction emphasizes the nature of EM waves as pure energy forms.

PREREQUISITES
  • Understanding of electromagnetic theory
  • Familiarity with the concept of accelerated charges
  • Knowledge of electric and magnetic fields
  • Basic grasp of wave propagation principles
NEXT STEPS
  • Study the Lorentz transformation of moving charged particles
  • Explore the relationship between charge and electromagnetic wave generation
  • Investigate the properties of sound waves and their analogies to EM waves
  • Learn about the nature of energy in wave phenomena
USEFUL FOR

Physics students, electrical engineers, and anyone interested in the principles of electromagnetic theory and wave propagation.

electromagnetic waves are created or produced by accelerated charge. but EM WAVES are chargeless? how is it? please clarify folks... thanks in advance

Why should there be a "but" in your post? Why shouldn't two different things just be different?
 
Hi,
In EM waves are just energy, So chargeless. [Lorentz transformation of a moving charged particle]
PS: EM waves contains only the fields (electric and magnetic).
 
The charge is simply the source of the EM wave. Once the wave is propagating, why should it still have the charge?

Let me put it another way:
Sound waves are created by vocal cords, but sound waves don't have vocal cords.
 
thanks a lot mr.comos. i understood it fully.
