At last! A proper explanation of propagating waves, wave number etc. Paused mid-vid to like!

[@heisangx]

Excellent explanation, in melodic and perfectly ennunciated English. Thank you.

[@AfricanThinker86]

Ah, I see. @3:01 Looks like the two waves are superposed on one another. The higher frequency wave is responsible for those smaller peaks and pikes while the lower frequency one is responsible for the 1 large peak and pike, which has a higher amplitude.

Thank you for defining dispersion in your presentation. Quantum computing requires this wave material.

[@mahmoudelgeziry5160]

That was very useful, thank you very much, Hilary!

[@speedbird7587]

Thanks for your brilliant video. I really enjoyed it.

[@amrwael8348]

Amazing explanation for dispersion , I have been looking for somrthing like that , thank you very much !

[@pranavshrestha2221]

Thank you for the concise explanation!

Dr. Weller your lecture notes are the best. I love how you always highlight the "take home message" of every section. The animations showed in your videos are very helpful. Any chance the scripts are available for download? I tried to look on bitbucket but couldn't find them. Anyway thanks so much!

[@hilaryweller615]

I have updated the links to the lecture notes. One set of notes for each playlist. Let me know if you have a problem finding them. I cannot guarantee that the lecture notes are identical to the videos. The notes are updated more often. Thank you for you kind words Hilary

[@adityabaghel1270]

Thank u very much too.

[@stevethepirate7890]

Thank you so much that was helpful !

[@shahzadkhan-xq3wb]

great work...best wishes

[@seanwilliams7968]

such a great video!

[@casualBob7]

highly appreciated video :)

[@whatitmeans]

The are any differences of using and envelope function f(t,x)=(1-(x-t)^2+|1-(x-t)^2|)^pi instead of a non-local gaussian function as the kind used like g(t,x)=exp(-pi*(x-t)^2) ????? My intuition is that the non-local versions will made struggles analizing a group-velocity-delay disperssion on change of medium where the kramers-kronig relations are involved.

[@hilaryweller615]

sorry, I don't know

[@aakashdewangan7313]

Thanks madam ... Liked it

[@daisyhung6851]

Amazing thank you.

[@MuhammadAwais-vi8de]

In lecture notes, I cant find equations for questions.

[@hilaryweller615]

I am sorry, I cannot answer that. Your comment is too vague. I have no idea what equations you are looking for or what questions you are referring to. I am happy to point out where things are in the lecture notes but not provide additional material.

[@MuhammadAwais-vi8de]

In the first slide, there is a question about wavelength and speed equations.. I was looking for that

[@tanmaykabi3883]

Is it an application that you are using to form these waves?

[@hilaryweller615]

Just a little bit of python code

[@tanmaykabi3883]

Thank you. Remember my name, I am going to be a great teacher

[@dr.mouhssinmaache1414]

great

[@king0vdarkness]

I had a quick question please can i ask: What is a lamb wave?

[@hilaryweller615]

[@dylanparker130]

thank you

Mam...why the love wave is dispersive...
