SUMMARY

The discussion focuses on demonstrating that the electric field E = E0 exp{i(k·r - ωt)} and the magnetic field B = B0 exp{i(k·r - ωt)} are solutions to Maxwell's equations in a source-free vacuum. Key equations include Div E = 0, Div B = 0, Curl E = - (1/c)d/dt(B), and Curl B = (1/c)d/dt(E). The relationship between the magnitudes and phases of E0, B0, ω, k, and c, as well as the directions of the unit vectors, is derived from these equations.

PREREQUISITES
  • Understanding of Maxwell's equations in vacuum
  • Familiarity with complex exponential functions
  • Knowledge of vector calculus operations (divergence and curl)
  • Basic concepts of electromagnetic wave propagation
NEXT STEPS
  • Study the derivation of wave equations from Maxwell's equations
  • Learn about the significance of the speed of light (c) in electromagnetic theory
  • Explore the relationship between electric and magnetic fields in electromagnetic waves
  • Investigate the implications of boundary conditions on wave solutions
USEFUL FOR

Students of physics, particularly those studying electromagnetism, as well as educators and researchers looking to deepen their understanding of wave solutions in Maxwell's equations.

Homework Statement



Show that the Fields E= Eo exp{i (k.r-ωt)} and B= Bo exp{i(k.r-ωt) are solutions of Maxwell's Equations in source free vaccum.Starting with maxwells equations in vaccum.
And there by Derive the relations between the Magnitudes & Phases of
Eo, Bo, ω, k, & c. And the directions of Unit vectors Eo,Bo,& k.

Hint( Should only need the fact that Del (k.r) = k .

Homework Equations



Div E = 0.

Div B = 0.

Curl E= - (1/c)d/dt(B)

curl B = (1/c) d/dt(E).

How to solve these Equations. to obtain the Electric & Magnetic Feilds.

Atleast give me Hint.. how to start this..

iam really trying hard on this...

Really? I couldn't tell from your post :biggrin:

Here's your first hint: read the question. (I've found that to be pretty useful myself) "Show that the fields \vec{E} = \vec{E}_0 e^{i(\vec{k}\cdot\vec{r} - \omega t)} and \vec{B} = \vec{B}_0 e^{i(\vec{k}\cdot\vec{r} - \omega t)} are solutions of Maxwell's equations..." Surely you can do that? Just plug them in and see what you get.
 
thank U very much diazona...
