8.2.4 Reflection and Transmission at Normal Incidence

8.2.4 of Griffith's Introduction to Electrodynamics 2nd Ed
EM Plane Waves approaching a boundary between two non-conducting linear media seems complicated, but it's really simple --- if you keep everything straight.

oh thanks for posting it,,,it was very helpful during my final terminal exam :)

[@herbertjamesbanda1084]

You so awesome Sir ... You saved a soul here

[@alaahesham250]

Thank you professor , you are to the point.

[@WalterParsons]

Sweet, man! Just cleared this up way better than my prof

[@ahmadzikwan5674]

really thnks sir its helpful to me in my presentation

[@nabeelidris2734]

Can the total electric and magnetic field in this case be discontinuous across the mirror surface?

[@ghulamhussainkhan7158]

could someone let me know how epsilon 2 v2 = n2. in the last equation.... thanks

WHY WE PUT NEGATIVE SIGN TO REFLECTED MAGNETIC FEILD

[@Anna-mt6yh]

I need a topic reflection and transmission at a boundary of non conducting media...plzz

[@drsid23]

Well done -- glad that you caught your error of T for I around 14 minutes. My handwriting looks a lot like yours :>

[@solarenergytraining750]

How is the perpendicular component of E and B zero?

[@sankhadeepgain4]

ET = 2 v2/(v1 + v2) you missed the v2 also the n1 in the corresponding equation

[@DS-tg8cj]

What is the relation between B and amplitude of E?

[@ariana5691]

Great video. Question, how could I find the intensities of the incident, reflected and transmitted waves? (I'm given R=0.5, f=500Hz, and pressure amplitude 2Pa)

For you everything is easy and trivial. I don't like your explanations at all!
