Kihan sir's work

I really wish these videos from khan academy india were integrated into KA's official physics course. They're so well done.

i love the way he teaches in his videos, with all the nessecary details and still not spoonfeeding. I request the viewers to actually pause the video when he instructs and try to solve what he says. If you are able to solve it gives you a whole new level of confidence and understanding

Pshhhhhh... Love the way he repeats what he have said in the previous videos! This shows me that he wants to convey every single concept without prerequisite (Subscribe, watch the previous videos, like...) true legend! Thank you indian brother🤩

Why is it so hard to imagine a wavefront

Particles in sync by vibrating at the same time with each other.... And the shape that appears if you look the thing from top veiw is basically the wave front.

It's pretty simple you just gotta see/imagine the waves carefully and you'll get the wavefront

Khan academy is revolutionary. Thanks guys

Great work thanks for making me to understand this concept

Thank you for the explanation. ive been watching many explanations about this from other youtube channel but still cannot fully understand because no animation was used. thank god i found this channel !!

YOU ARE THE BEST PHYSICS TEACHER I'VE EVER GOT.. LOVE YOU SIR

Thank u verrrrrry much for this ❤❤

This is first KZread channel in I understand the concept perfectly thank you sir ❤

Why don't they teach like this at schools ?😭😭

Amazing way of explanation ❤️👍🏻

Thanks a lot , Sir.

You are actually an excellent teacher .... Love you physics Thank you sir....

this channel literally saved our lives. thank you so much!!!

Amazing ..hats off to you for this beautiful explaination 👏

Bro made me understand which my 5 physics teachers couldn't do

I was struggling so much, THIS IS SUCH A GOOD LECTURE!!!!

you teach exactly the way I want to learn Physics. Love you, sir. Wanna know more about you.

Yeppa super da

U teach awesome and the way u explain the concept makes bored topic intresting thank you so much

Great work sir....👍seriously feeling encouraged and hopeful whenever I hear ur voice 😇

Goated video just fits the whole concept in my mind with in minutes

Simply, perfection 💜

Victory for huygens

Dude you are god of teacherssss . ..🌩️

Outstanding sir

Finally I got it I am crying 😭

I feel God blessed me with this amazzzingggggggg videooo😭💘 Brooo u areeeee sooooi goooooddddddddddddd😤😤😤👍🏾👍🏾

Thankyou so much for clearing my concept....This was just precise n amazing💫

thank you so much sir, i find so difficult to understand the diagram at first but now I've understood very well after watching this 🥰👍🏻👍🏻👍🏻👍🏻

I love it. You are amazing.

superb

Awesome... Really thank you❤❤❤❤

Very nice sir science is made easy by you.

Awesome👍

Please add this video to the wave optics playlist also make videos on another topic of this chapter because the way you explain makes me love physics ❤❤😀

he has already done that on his website

Light is not really slowing down if it enters an optical denser medium like water but it's the interiaction with the medium which is called group velocity is less than its normal velocity called the phase velocity.

Super explanation

Thank you sir

Hey Master! You are just great !!!

better then school lectures dude literally solved the confusion like it was nothing

Using the same triangle if i calculate the cos i/cos r i get the constant , is that also right?

AWSM :)

I saw a video on Fermilab which basically says that you can't use Huugen's princple to determine the correct path of light through the second medium because you can align the wave fronts in *several ways* in the second medium, only one of which agrees with experimentation. To understand and derive Snell's law correctly, it looks to me like it is necessary to deduce this law from Maxwell's equations.

DOES THE INTERFACE ACT AS A HUYGEN SOURCE OR IS IT THE INCIDENT WAVEFRONT WHICH ACTS A HUYGEN SOURCE...PLZ EXAPLAIN🙏🙏🙏

I believe it is the wavefront since the secondary waves originate on the wavefronts emitted by a luminous object.

Stop screaming 😱

at 10:58, if it has a slower velocity and speed, shouldn't it take a different time, thus the statement in the video false?

@the__saksham

3 жыл бұрын

no the velocity maybe different, the the time is same. when the endpoint of wavefront touches surface in time 't' then the wavelet produced from the first point will propagate in that time t.

How are time taken equal?

I have one question : when finding the distances, why is the time same for both??

@someones2413

2 жыл бұрын

because they are travelling at the same time, one is just further. We are taking a set time frame and saying that one travelled with a distance of v1t and other with v2t

why will be the time be same in 11:08

An eletromagnetic field that is waving but not like normal waves like waterwaves but waves that come in packets called photons.
