The beauty of mathematics and physics confirming that light is indeed oscillating magnetic and electric fields.

your channel is ultimately underrated. thank you!

[@Neamhain97]

This is so clear and helpful.. I'm impressed. Thank you for your help Professor

Dear Jeffrey, I have a question: In your example you eliminated the B from the 3rd equation and the result was a wave equation for the electric field, e.g. an electric wave. But since we are speaking about electromagnetic waves, shouldn't there also be a wave equation for the magnetic field as well?

[@paokaraforlife]

yes if you do the same process but start from equation 4(the curl of the magnetic field) you end up with a similar expression for the magnetic field

[@ernestschoenmakers8181]

@@paokaraforlife The magnetic field has a smaller amplitude than the electric field but both are in phase with each other.

Thank you, Prof!!!! Now everything is clear for me

[@lawrencecohen1619]

Thank you. A very well explained derivation of the wave equation from Maxwell's equations

[@len5755]

thank you sir!

[@nirvana12360]

Very good video, explained it far better than my lecturer.

Big thanks from Iraq 😇

thank you

[@AngieGuzman]

thank you!!!!!

Your video is incorrect, you must add the concept complex permitivity to reduce de curl B ecuation to ue dE/dt. Moreover it is important to add the fasor terminology to explain correct.

What?

V.E= Q/eo

[@ProfJeffreyChasnov]

Free space, no charges

[@mohammadfahmialalam9784]

why the miu 0 and epsilon 0 became denominator?

[@andrewk2625]

Because they are transferred to the other side of the equation. Or another explanation is - both sides of the equation is divided by meu and epsilon naught.
