I bilieve that this is the Mosr Underrated channel, It is so informative and so east to understand, Stuff that takes hours to be explained in class is explained in minutes here. Thankyou So much KhanAcademy Team!!
this is the first time i had to step away from my always go to tutor channel bec for the first time I couldn't understand their explanation about Huygen's....then I found this. Oh my gosh with the animations and everything thank you so much !! it is so thoughtful and thorough!! I can't visualize it so this really is so clear.
Amaaaaazinggggggggggggg First vdeo that make me understand in one shot Although i m starter 10th, still i understand 90%, that left 10% is of terminology and rules fr waves behavior like it should be perpendicular, wavefront, active pointd etc. Bt i m sure as soon as i learn abt them it will be crystal clear fr me 😄😄😄😄 Thankkk u sirrrrrr
from 0:32 to 0:52 the purple vector is not normal to incident ray's wavefront. So in the end, the angles of directions (purple and yellow) dont seem equal.
The sum of a triangle is equal to 180 degrees. We have a 90 degree and a (90-r) degree. For that reason the missing angle is equal to r because 90+(90-r)+M(missing angle)=180 => M=180-[90+(90-r)] => M=180-180+r => M=r. I hope that you find it helpful.
Why is this video so underrated?????this is the perfect video for this concept
Imperfect logo ko perfect chij smjh ni aati isliye
yes bro, if i could found this video earlier my exams might ended up good
It's due to thumbnail
Ikr this video is literally a GODSEND
True af bro
1:40 finally found the use of setsquare.
lmao
Lmao
This was so good, you made it really clear to understand. Thank you so much!
Really appreciate it
0:36 getting goosebumps.
Thanks for such a clear concept.
Same here. Really it's very clear. 100%. After seeing this, I've no doubts💯

These India Khan Academy vids are always excellent
thank you sooooooooooooooooooooooooooooo much
If We had great teachers like this in Every indian schls , Imagine the level of the development we would reach in the upcoming decades .....
This is an awesome lecture, clear and pleasant presentation. Thanks!
This is called killer visualisation
Rocking bro💯💯💯💯💯

different type of teaching....
unique..
What a wonderful animation this is!
Fantastic!
Mind blowing animation.

It was great...
Made the concept clear...
Thank you sir....
WOW,Sir...Thank you soo much
Thank you do much
Amazing illustration
Excellent
Khan academy ❤Thank u so much...My teacher is useless, bruh I didn't learn anything..i am not dumb if was I then I wouldn't understand this video...
Super teaching
The best way of teaching. Absolutely Mind blowing!!!!
Sir aapke saare video kaha milege
Animation is amazing . Specially 0.47. It's just like a real feeling as if everything actually happening in front of me (3D) Thank you
finally i understood this topic
Thanks man
Great.great.great
Wow I'm not a science student and i got it. Brilliantly explained
Pure like a 1000 kg/m3 density 💧🚰🚿
People have to pay to watch this video!
No one could have taught this to me this crystal clear
Thanks for the awesome video. Thank you sir
YEAH....ANOTHER ONE❤❤❤❤
Best explanation I have ever seen on this topic. Thanks a lot.🥰🥰🥰
Where is the donate button?
At 8:30 can someone explain this if outside angle is r and one inside angle is 90-r and other inside angle is also r?
I got the answer thanks..
I think physics is all about understanding the concepts, Thank you for making the concept crystal clear.
What do you mean by Huygens source getting activated?dosent it always remains activated
Salute my bro
Seriously I understood each and every thing 😀😀thank you..
Booyahhhhh🔥
Why reflected and incident wavefront have same speed
Because they're in the same medium.
Sir will I be able to get your all 12th class videos by Jan 2021
Sir, Which software you are using?
Amaaaaazinggggggggggggg
First vdeo that make me understand in one shot
Although i m starter 10th, still i understand 90%, that left 10% is of terminology and rules fr waves behavior like it should be perpendicular, wavefront, active pointd etc.
Bt i m sure as soon as i learn abt them it will be crystal clear fr me 😄😄😄😄
Thankkk u sirrrrrr
Victory for Huygen
Thank you...... really a great help
By the way, which software are you using for explanation.
Reply would be greatly appreciated!!
Thank u once again
Nice 👍👍☺️
❤❤❤
Great explanation sir, 👌 👏 😀 🙌 I have ever learned this chapter in this was.
Wait how does the mirror produce 2° waves???
reflection
from 0:32 to 0:52 the purple vector is not normal to incident ray's wavefront. So in the end, the angles of directions (purple and yellow) dont seem equal.
LOVE YOU 3000000000000000000000....
Thankyou
Really fantastic
❤
AWESOME EXPLANATION!! Just what I was looking for. You are a gem of a teacher.
Ye dislike krne wala kon h bhai🤦🤦🤦
Great channel with lots to learn！
But the angle between i&r is 90
Bismoi is brend Embesiter
Can someone explain me how the angle between surface and the reflected wavefront = r
The sum of a triangle is equal to 180 degrees. We have a 90 degree and a (90-r) degree. For that reason the missing angle is equal to r because 90+(90-r)+M(missing angle)=180 => M=180-[90+(90-r)] => M=180-180+r => M=r. I hope that you find it helpful.
Thanks a lot man! Now i understand it clearly
@@ΒασιληςΧουνταλος thnx 😁
Great, thanks. Besides this point, the video is flawless.
Khan academy sir says; booyah😅😅😂😂
Send your I'd sir(; it's true any one abserve?????
Free fire I'd !!!!!
Cleared the doubt
your way of teaching is totally awesome 😎👍🏻
Love you bro
Q. Light assummed a ray is for ray optics but here in wave optics, we still have rays together wavefront...🤷
AAA congruency rule would have been much easier to workout. But, anyway the video was wonderful.
Creed
Fascinating ❤️❤️❤️
Of course it’s Khan academy with the quality uploads! ❤
Sir Seriously woww Best teacher of physics I would say ❤️❤️
Too good...thanks🤎
Understood the concept clearly 🤝
It's great thing about you sir that you motivate us to think and and Prove the conclusions by our own
Everything is perfect well illustrated . Thanks sir for sharing ❤
Thank you
Which software you are using to draw the diagrams sir?
wow
Thank you so much!💜💜💜💜
♥️♥️♥️
I am really amazed by your teaching style 😮😯
Best vdo of this concept ❤
I swear to god, this chapter is gonna be the death of me
Perfect explanation
This is enough for neet?
I have seen lots of videos in this same topic and it's the best to understand concepts.
fall in love with the concept... thx for efforts
Sir on which application you teach.
Thank you so much
Huygen says...
This video is so good! 😭
Thank you
nice explaination
You just saved my 1hr
Thnks a ton sir ❤❤❤❤❤❤❤
Thank you sir
That the teaching
Wow! AMAZING!
Semma vroo
Hats off🤓
