life saver - basically learnt a whole topic in 30 mins before my exam

Excellent summary, thanks. A couple of small points to note (for those that study OCR certainly) when he says the antinode is the place of maximum displacement be careful of how you define antinode in an exam. Better to say the antinode is the where the particles experience a maximum amplitude or the place where the maximum displacement is maximum. All points between nodes will displace to a maximum displacement, but the amplitude varies to a maximum at the anti node. Second point is where he mentions coherent waves when begining on interference/diffraction. He says they are coherrant because they are in phase, that could be misunderstood as a valid definition of coherent. The bit he says after is actually what makes them coherent - they have a constant phase relationship. The amplitude being similar is not relevant to coherency (but is relevant to the diffraction pattern produced). Otherwise an excellent an excellent account!

i beg you someone tell me why lewis has taught me better than most my teachers in a single video

i was struggling to find a full, comprehensive guide on the subject, this is exactly what i needed, thank you! :D

Very useful!! Best use of my time on KZread ever :)

Thank you so much for doing full topic videos!

Well,I have to say this was the most concise video on yt about waves.

Please do this for electricity this was amazing

Thank you sir! You made me love waves.

Watching this after finding about your channel on a crowdcast physicsinaction lecture , this is awesome stuff!!!

I build LEGO as a hobby so seeing the little brick made examples makes revising so much more bearable :) Thanks for the video!

So useful. Explained it perfectly thank you 🙏

Please could you do a video measurements and their errors? We’ve missed the estimation of physical quantities bit (orders of magnitude etc) and having all of the uncertainties stuff would be great. I really like these videos

Incredibly helpful and engaging right the way through. I've only got a few months left before my exams and my biggest regret was not purchasing the resources on the website earlier! I'm definitely going to be letting my younger brother know about it, as he's starting his A-Level course in September! Thanks again.

Really appreciate your work and i loved it that you are literally saving students from dying in their exam halls while doing waves , I had a favour to ask , that is can you please give me a pdf of scanned copy of this chart or any other charts you've made earlier , that would help a lot ! thanks !!!

Hello and thank you for all of your videos thus far, but would you be able to make an even higher level physics course??? Ones that cover the wave equations as well as the calculus based portions of physics. That would be awesome.

God Bless you sir!
