Science Shorts: 6:40 *BIG D*
literally came down to comment that
we are getting unlucid just put phone away
oor watch it
@@tahmidahmed6524 same
I thank you for making such a well explained video but i lost it when he said "BIG D" 😂😂😂😂
Juwariah Ahmed me too!!😂😂
It killed me 😂😂😂😂
i still fail to understand how his voice changed so suddenly
As soon as I heard that I went to the comment section and surprise surprise, you mentioned it with timing! 😂
@@desirefun6914 dopler effect😂😂😂😂
If anyone has any money they can donate they should. Not all heros wear capes. You are a legend good sir.
I can't donate yet but once I make it in life, it will be partially thanks to this man and I'll donate as much as I'll be able to. He totally deserves it.
glaze
am i the only one who loves the way he writes and draws
First channel Ive found with Physics A Level videos without a boring, dull voice-over😂. Thank you!
+Toby Caunce Hehe, thanks! :)
The feeling's mutual mate!
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
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.
6:40
YEET
the way he said that :D
I learned from you rather than spending loads of money to classes
Great teaching sir 👍
You can always donate to help me out 😏
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 !
The explanation of path length and its dependence on constructive and destructive wave interferance was really amazing. Thank you
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
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.
"BIGG D" xD
i thought i was the only one who noticed it lmao
god bless you, you just explained grating better than my textbook and my teacher combine, 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
the only physics channel on RUclips, that i could find, which actually explained these equations
I love this dude
Teaches so well yet, isn't boring in class lmao
Please teach more, definitely my favorite teacher.
Big D
Thank you so much for posting these videos! Your videos help me much more than other sources.
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.
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
I have this next week lol, how did it go? (even though it was 4 years ago)
@@ize2543 I got A levels physics paper 1 tomorrow 😬
@@M_aak how was it
@@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.
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.
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
6:39 I like lessons where the teacher also has fun!
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
Just wanted to say that that was so helpful thanks
+Doppy C Thank you - glad you find it helpful!
This is incredible, you are saving my future
You explained it very smoothly. Thank you!
bro, i love how you got right into it.
this is excellent teaching. i hope and pray you have more similiar content
i can't express how much this helped thank you
Wow, finally a video that explains things clearly. Thanks !
6.40 best moment and it's not even mechanics...haha banter
Thank you for the video once again, it’s so useful for just a reminder after the holiday
YOU ARE A LIFE SAVIOUR. THANK YOU SO MUCH.
Incredibly helpful! Thank you so much.
Oh my god, you don't understand the eureka moment I had when I watched this video. I finally figured out diffraction thanks.
Sometimes the book is unclear. You solve that issue. Thanks boss!
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.)
Amazing videos thanks so much and if I get the grade I need I'll be donating on results day!!
This is such a useful video thank you so much!!
So satisfying to watch you write.
Really appreciated. I was about to fail my mock but u saved me. Thank you for such an amazing video ❤❤❤❤

Beautiful explaination. Thank you good sir.
This is remarkably helpful. Thank you
Thank you sir
I might just have a shot at the physics exam tomorrow
this video saved my life ish tq for the detailed explanation
You're simply amazing! Thanks!
Thank you for the videos, they're extremely helpful
Thank you so much! I finally understand this.
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)
6:40 Im done XD.
gagahahahaI CHOKED AT BIG D
also please do some worked examples for this? Pls pls
@@jibran8410 F
Very helpful. Thank you. 👏
you’ve finally invested in a ruler! :D
thanks for the video but how do you produce white light fringes if only monochromatic light emerges from the single slit
thank you SIR science shorts i appreciate the amazing work my teacher is so slow
Amazing video!!!!!! So helpful
love these helpful videos, is possible you could either make some or link some videos on astrophysics as that the the choice my school is doing and struggle alot with it.
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!
Thanks man, super helpful!
Nice show！ Thanks！
The video helped me sooo much Tysm 🙌🏾
Helpful video. Thanks
This was very clear thank you
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
@@hashbrown1235 excellent!
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 :)

@@altacademyorg thanks I wasn't aware of that. I think I'll utilise your past paper seasons
You are awesome man!!
Very helpful, thanks!
this is amazing thank you
you are a lifesaver 😁
Thank you 💕
You sir are a legend
sir all is well but it would be grateful if you had explained the effect on bright fring if some conditions is changed or any other changes....
YOU ARE AMAZING!!!!
Amazing very helpful. 👌
In the interference pattern for a single slit, what do you mean when u say the single slit is double the width of the fringes. And is the central max brighter compared to the double-slit central max?
Thank you so much for this vid
15:02 i don't have to make any changes as my slit width says "YOUNG'S SLITS WITH 0.1MM SEPARATION" other than changing it's unit to m?
So helpful. Thanks
Thank you lots!
I guess all Zimbabweans are proud to have a teacher like u trust me they do😊😊...lol
Sending some love from Zimbabwe 💝
Thankkkkkk u soooooo muccchhh forrr thissssss. 🥰
so to find the wavelength, you just measure the spacing between the bright spots right?
Could you use the probability of them going through several slits at a certain probability to amplify, or confine a laser beam?
Could you explain the proof for the diffraction grating equation because it is on our spec to know it? Your videos are sooo helpful btw.. don't know where I'd be without them
Thank you so much! Tomorrow I am having an a level exam. I was struggling with this topic and you made it soo clear!
How did your exam go?
Yuri Boyka very well. Easier than I expected
@@zuhramajid nice..where u from btw?
Yuri Boyka Kazakhstan
Yuri Boyka U?
Amazing videoooo!!
Am I the only one who appreciates how he utilized all of those marker colors
Top man thanks
thank youuuuu sirrrrrrr
Does this series involve As level topics or both As and A2 level topics together?
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.
Thanks!
who s watching this few days before physics paper :((((
Mine is tmrw XD
today..
a day before my P2 :'/
Well, its 9 am and exam starts at 11 am. Beat that
a night before 🙃
how come the fringes for the single slit is smaller than the fringes for the double slit
14:47 *Demonetized*
thank you so much
4:44 the path difference is one?
