Electromagnetic Waves - IB Physics

I go over the basic properties of electromagnetic waves: why EM waves are transverse traveling waves, how they are created, and the types of electromagnetic waves on the EM spectrum: radio waves, microwaves, infrared waves, optical waves, ultraviolet (UV) waves, x-rays, and gamma rays.

Thanks mate, just studying for my physics mock which is tmr, and this series is a great review on topic 4!!

[darkorse]

Fantastic explanation.
You have a way with words, my friend.
Great job.

Thanks brother, its simple, for understanding the principle.

Thank you! Do you plan on doing videos on the HL topics?

Thanks for the great explanation. Just wonder if you think I should memorize the EM spectrum as I believe that it is not provided by data booklet. Thank you!

The electric field and magnetic field are NOT in phase. They do NOT exist simultaneously. This theoretical problem has exist for over 150 years and it seems that even when experiment proves theory incorrect (see 2012 article) we still don't change it. This theoretical "unification" of the electric and magnetic field is the reason we don't have a Theory of Everything today. It is also the reason we have infinities in our mathematics. Read The Feynman Lectures on Physics Volume II (Chapter 28) to get a better idea of this problem which was never resolved. He doesn't speak of the phase of the electric and magnetic fields, rather he discusses the self energy problem which is related to this concept.
