    Maxwells equations
AI Thread Summary
The discussion focuses on demonstrating that the electric field E and magnetic field B are solutions to Maxwell's equations in a source-free vacuum. Participants emphasize the need to apply Maxwell's equations, specifically the divergence and curl equations, to the given fields. A hint suggests starting by substituting the fields into the equations to verify their validity. The conversation also highlights the importance of deriving relationships between the magnitudes and phases of the involved variables. Overall, the thread encourages a methodical approach to solving the 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..

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...
 
Thread 'Help with Time-Independent Perturbation Theory "Good" States Proof'
(Disclaimer: this is not a HW question. I am self-studying, and this felt like the type of question I've seen in this forum. If there is somewhere better for me to share this doubt, please let me know and I'll transfer it right away.) I am currently reviewing Chapter 7 of Introduction to QM by Griffiths. I have been stuck for an hour or so trying to understand the last paragraph of this proof (pls check the attached file). It claims that we can express Ψ_{γ}(0) as a linear combination of...
