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 :)

What is the main difference of using sometime μ and something μ0 . I have such a confusion on this thing?

[WalterParsons]

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

[nabeelidris]

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

[abhishekpanwar]

WHY WE PUT NEGATIVE SIGN TO REFLECTED MAGNETIC FEILD

[solarenergytraining]

How is the perpendicular component of E and B zero?

[herbertjamesbanda]

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

[Anna-mtyh]

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

[ghulamhussainkhan]

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

[DS-tgcj]

What is the relation between B and amplitude of E?

[sankhadeepgain]

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

[ahmadzikwan]

really thnks sir its helpful to me in my presentation

[drsid]

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

[rajatligade]

At 3:50
why is there a negative sign for B and not for E?
I did not really understand your explanation for that

Thank You

[alaahesham]

Thank you professor, you are to the point.

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)

[veronicanoordzee]

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