6:57 For help with the algebraic manipulations: Based on the first equation, substitute (AI + AR) for AT in the 2nd equation and then solve for AR. Likewise, solve for AR in the first equation and substitute that for AR in the 2nd equation and then solve for AT.
This was really helpful. You could've also helped with the algebraic manipulations. Since i have to present the seminar paper tomorrow Thank you for helping me :D
Ehh... I don't know how to simplify this. Am I talking too fast? What words are you unfamiliar with? I know that English is a tough barrier, especially because my American accent isn't very common in academia. If there's a particular section in the video that is hard to understand -- point it out I can improve and do better next time, or perhaps explain it here.
I vaguely recall struggling with how to explain this. Basically, omega says how fast the wave is wiggling back and forth. If they don't wiggle at the same rate at the boundary, then you can never find a solution that will satisfy the condition that they must be equal at the boundary. Imagine you're waving a rope, and on one side, the rope is thin, and the other side the rope is fat. Even though the wave velocities are different, where the two kinds of rope meet, they must wiggle at the same rate, otherwise the rope would be cut.
4:55 very useful point. Even I got doubt about it. Finally in this video clarified
Thank u sir
Thank you very much for making these videos I really appreciate your hard work

Thank you for helping me :D
your videos are great! actually real physics
This was very helpful, thanks! :)
It is very heplful for us...i am showing this vedio from bangladesh
Thank you and I hope and pray for your success!
You are the best!!!!How are you so fucking good!!!Thanks man.Love from India!!
k1 - k2 is equal to v2 - v1? not v1-v2?
Your videos are helping a lot .but plss explain in simple language

Really helpfull.....
at 4:06 I didnt understand how you deduced that the omega's are equal

thanks, great videos!
@@jg394 Is there a mathematical way to state that?
@@aviralsingh7746 Yes, set the omegas equal.
What is e^idelta here what is Delta
Best explaination but please can u try in hindi..?
