I used to hate electricity...then I watched your videos on it and now have a new found love for it. I used to hate waves, I’m currently watching your videos on them and I have a new found love for them. Thank you.
Thank you for making our lives easier ! You're one of the best teachers ever ! You explain the difficult concepts in such an easy manner... Love you for that sir. I'm done with your waves series and now I'm moving on to electricity. This world needs teachers like you and Mr. Walter Lewin.... Hats off to both of you !
Oh my word. You have no idea how much I struggled with this experiment exam question. I went to websites to text books and I still get very confused. You saved my life. Your video is amazingly detailed and organized. Hopefully, I do well in the predicted grade exams. Thank you very much :D
@@jozifff. meh it was alright, some questions were good but others not so good, like the waves question about the prisms and finding distance X for the ceiling ligts.
Thank you for your whole series on physics, it was well presented and you've made it simple to grasp the concepts. Even though it was aimed at A levels. I used it to understand the concepts required for MCAT.
Biology Teacher here with a son struggling with physics. Has been very helpful for him to see how to apply experimental data to calculate wavelength. Thank you.
Your explanation was fantastic . Till the last moment of watching this, I scared of these wave stuffs. But watching this video has made my concept clear. It makes me to smash the face of my physics teachers the way they explained such as interesting thing. God bless you brother
I'm only 1/4 of the way through and you have already clarified three things that were skipped over by several other sources! (Get the word out, somehow. Remember, you may have the better mousetrap, but if nobody knows about it, neither you, nor those in need, will reap the benefits. Love, from across the sea.)
For A-Level pupils in my last job, I built a device that demonstrates De Broglie’s theorem. A laser passes through a diffraction grating creating an array. A motor spins the diffraction grating to produce the rings
We did a practical before learning much theory on diffraction gratings, and I'm pleased to say I understood what we did then, having watched this. The switch from Young's equation to this n x wavelength = slit width x sin theta makes all the more sense, and I understand the reciprocal relationship between 'D' (grating) and 'd' (slit width) now. Other useful pointers received from the video, so thank you very much :)
The AQA A-level spec also mentions that students should know uses of diffraction gratings - one is xray crystallography, which is used to identify elements. This is also how DNA was discovered (by Watson and Crick, I think)
Thank you so much for making these videos they’ve been so helpful for me. Makes me wish I’d found them earlier when we were doing the topics in class so I understood it better then
Hello there, I would just like to say (from an A level teacher point of view) THANKS!, these videos are golden, my students are high ability year 12's and these videos have been amazing for them over the remote learning period. I have been setting them with the required practicals and they are great summary videos to watch as part of a more interactive independent learning lesson...Great work! Thanks again.
See, thing is we were never told that the equation used assumes a curved screen, which is why I find this topic so confusing, as the usually explanation makes no sense on the scale that we draw it at, and if you try measuring the actual lengths in the diagrams, the maths won’t work out. However on the scale of actual wavelengths of light and slit separation, we can make assumptions and approximations as it makes much less of a difference.
Please could I suggest a video on Archimedes principle. Also, Springs and Hooke's Law. Thank You. I have watched nearly all of your videos for a level physics and it's really helping!
THANK YOU for explaining D vs d, every other explanation I've seen has completely glossed over how to convert "xxx slits per mm" into the number you put into the equation so that was super helpful!
18:25 i thought the maximum number of orders would be the number of visible orders, therefore 5? so the maximum number of orders as opposed to the maximum order, which would be 2. confused by aqa's phrasing, as usual.
you missed something in the end. n at 90 degress are, 2+2+1. 2 order 90 degrees downward and 2 order 90 degrees upward and including the zero order makes 5 orders in total
Well, yes, it depends on how you define "max orders" - could mean max n, or total number of orders. But you're right, quite often questions will try and catch you out on this.
At 2:30 are you absolutely sure this is true, as I've come across exam questions where it says that white light shone through a single slit then a double slit , forms a dispersion spectra on the wall.
Absolutely no one:

I thank you for making such a well explained video but i lost it when he said "BIG D" 😂😂😂😂

the only physics channel on TH-cam, that i could find, which actually explained these equations
god bless you, you just explained grating better than my textbook and my teacher combine, thank YOU
I love how he’s trying to act innocent and ignore at comments who talk about BIG D
I was being genuinely naive when I said that 😭
AHAHHA
you have single headedly saved my science grades. literal living legend. thank you so much!
I learned from you rather than spending loads of money to classes
Great teaching sir 👍
You can always donate to help me out 😏

Biology Teacher here with a son struggling with physics. Has been very helpful for him to see how to apply experimental data to calculate wavelength. Thank you.
The first 20 seconds gave me a better explanation of why waves diffract when going through a slit, than my teacher could in 2 lessons.
Just wanted to say that that was so helpful thanks
+Doppy C Thank you - glad you find it helpful!
"BIGG D" xD

Love this guy man, I am always like 5 or 6 marks away from A* and all I have problem with is diffraction, thank you man really appreciate it
I love this dude
Teaches so well yet, isn't boring in class lmao
Please teach more, definitely my favorite teacher.

Its a joke how easy you make this seem than compared to when my teachers are explaining. Your videos are keeping me afloat right now.

6:39 I like lessons where the teacher also has fun!
This is incredible, you are saving my future

YEET
the way he said that :D
The explanation of path length and its dependence on constructive and destructive wave interferance was really amazing. Thank you
Wow, finally a video that explains things clearly. Thanks !
YOU ARE A LIFE SAVIOUR. THANK YOU SO MUCH.
These videos are amazing, my teacher is honestly really bad at teaching, and I have one week left to the exam. This is helping a lot
Same here 😥
How was the exam?
3 years since that exam
@@mohammedursalaan I passed A levels physics with an A* so pretty well I would say

Thank you so much for posting these videos! Your videos help me much more than other sources.
6:40 Im done XD.
bro, i love how you got right into it.
Oh my god, you don't understand the eureka moment I had when I watched this video. I finally figured out diffraction thanks.
this is excellent teaching. i hope and pray you have more similiar content
Thank you sir
I might just have a shot at the physics exam tomorrow
Really appreciated. I was about to fail my mock but u saved me. Thank you for such an amazing video ❤❤❤❤
Sometimes the book is unclear. You solve that issue. Thanks boss!
3:40 lmao did no one else notice the noise in the background?
So satisfying to watch you write.

Yes, you're right. Exam boards ignore the fact that a full spectrum will not enter the double slit.

thank you so much
First of all, it was amazing! I really understood a lot.
Did you really have to emphasize the "big d" part? I lost it when you said that lol
STFU YOU'RE BORING!
Thank you so much for this vid
this is amazing thank you
Big D energy right dere
So helpful. Thanks
Amazing videoooo!!
You are awesome man!!
thanks for the video but how do you produce white light fringes if only monochromatic light emerges from the single slit
