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!
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.
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
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 !!!
Omg you're only Yr 8 and you're watching an a level physics video? Haha don't worry you have loads of time to prepare. My brother is in Yr 8 and he spends all of his time playing games, he's not even thinking about gcses yet I wouldn't worry. I've got a waves test tomorrow and I'm doing some late night revision just before so if you're revising this early I have no doubt you're gonna do fine :)
Thanks for making this video. What about polarization especially on microwaves. The quite tricky this is because. I don't but are they partially plane polarized when they are emitted from the transmitter.
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.
Thanks, i really need these types of videos, with paper 1 less than 2 weeks away it helps having everything together in one place so i know im not missing anything. Will the rest of the paper 1 topics be out before 20th may? Also will you have paper 2 revision?
Hey man, i can't seem to find these large revision videos on your website Do you still make them for y13 topics, and if so could I get a link please? Thanks
Woah this video helped out my mandem in sixth form cause they actually went to sixth form in 2021 LMAOOOOOO imagine not going to college so you have to do A level physics. But this video must have been really helpful cause my smart mate recommended it to my less smart mate who said hes gonna give it a watch tommorow cause they want to pass sixth form physics as it is totally helpful for them in life

i beg you someone tell me why lewis has taught me better than most my teachers in a single video
Very useful!! Best use of my time on RUclips ever :)
i was struggling to find a full, comprehensive guide on the subject, this is exactly what i needed, thank you! :D

Well,I have to say this was the most concise video on yt about waves.
THANK YOU, This is rhe chapter ive been delaying doing
Thank you so much for doing full topic videos!
I build LEGO as a hobby so seeing the little brick made examples makes revising so much more bearable :)

You are a lifesafer Lewis! THANK YOU SO MUCH! You just cleared up a topic I had such a hard time understanding. Wish you the best

You made me love waves.
Please could you do a revision video like this for Mechanics and electricity
Already planned!
Good job you can tell he takes pride in his videos
Thank you soooooo much for helping me revised a lot in wave chapter, I might feel more confidence during my first mock
This is an unbelievably good video please can you do one for particles of light
mocks for my predicted grade for next year monday thanks for this nice recap
This was so useful! Please do this for electricity, mechanics and materials
I will, I promise!
This was amazing! Please can you do an electricity one?
Brilliant video sir, you condensed the information, making it much easier to assimilate. Better than my bloody teacher.
So useful. Explained it perfectly thank you 🙏
Thanks! i have my a-level exam in 4 hours so v helpful!

Watching this to prepare for year 12. Not going to lie, a bit scared. 😬
You’re not the only one, but it’s going to be alright!
Even worse now that we didnt get the second half of y12

i shoulda prepared myself for this.
Amazing thank u very much for real you are better than text books and teachers I have watched it like 4 times
i have test on wave comming up. it really helped. thank you
Hi Sir,
Will you be doing a revision video on y12 aqa particle physics?
Many thanks for your informative revision videos
Are you doing any ocr videos before 20th may?
This was pretty damn good thnxs
Another excellent vid. Thanks.
god send mate
Great video, really well explained👍
Do you make any of these for full A2 content, I have checked your RUclips channel and the premium videos, I cannot seem to find any.
I'm afraid I don't have them yet for the A2 content.
Could you please do a similar video for AQA Particles?
Could u do this on quarks and particle duality pls
thank you so much!!
thank you for making this video is it suitable for edexcel?
This is for 9702 right ???
Can you possibly make another one of these videos on other topics because I find them so useful
Of course!
Physics Online thank you☺️
Did this guy do the talk at Warwick uni??
I did!
thanks alot man, hold up im just gonna go on my roof and turn the aerial, brb;)
time to do some pre-emptive studying before going into college!
22:22 Sir, why is that distance lander?
God Bless you sir!
are you doing one on fields ? that would be so useful!
his fields ones are A2 so youll have to pay for a subscription (well worth it) but if not try Science Shorts on youtube
Ur a life saver
Love your video's, super helpful. Could you possibly do one for AQA a level Particles?
very helpful thanks. my as physics paper 1 exam is on the 14th may, will all your as videos be out before then?
oooo do you do edexcel because that’s when mine is

It can also be called "velocity = freq x Lambda" referring to the velocity of the wave!
Thanks for making this video.
What about polarization especially on microwaves. The quite tricky this is because. I don't but are they partially plane polarized when they are emitted from the transmitter.
They come out of the transmitter polarised
Hi! Is the content taught here similar to CIE A-level physics? Thanks so much btw!
When will the ocrb version be put?
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.
Please do this for other topics!

Amazing videos especially these summary ones, please can you do other topics as well
More will be added!
can you do this for edexcel ?
To reduce pulse broadening cant we reduce the critical angle
Does this work for OCR spec as well?

My question is why in single slit you get a central maxima and interference in the first place does it reflect back and produce a stationary wave?
U just gotta accept it XD
is this ok to use to revise for OCR physics. It basically looks the same
