Oh my god 🤣🤣
Balle balle !!!!
Thara rara 🎊🎊
Peace ✌️
A question that always comes in my mind is finally going to be solved!! 🤩
So damn excited for it! 🤓❤
Me also.
sir bas physics hi daalte rho aap.....pata hi nhi tha ki aisa bhi koi soch sakta hai...meri taraf se ek quote ..."we know that light travels better than sound , that is why people apper bright until we hear them" ....has a message in it ...😃...mind blowing sir...agle video mein na . .aap starting bhot se lambe aur mushkil english words se krna ...jaise the equanimity of incomprehensible personalities is such an bewunstesienlage ..😝...but I have wrote the spelling wrong the right one is something else.
Compton effect, because it helped prove that photon momentum is given by
p
=
h
λ
, where h is Planck’s constant and λ is the photon wavelength. (Note that relativistic momentum given as p = γmu is valid only for particles having mass.)
We can see that photon momentum is small, since
p
=
h
λ
and h is very small. It is for this reason that we do not ordinarily observe photon momentum. Our mirrors do not recoil when light reflects from them (except perhaps in cartoons). Compton saw the effects of photon momentum because he was observing x rays, which have a small wavelength and a relatively large momentum, interacting with the lightest of particles, the electron.
EXAMPLE 1. ELECTRON AND PHOTON MOMENTUM COMPARED
Calculate the momentum of a visible photon that has a wavelength of 500 nm.
Find the velocity of an electron having the same momentum.
What is the energy of the electron, and how does it compare with the energy of the photon?
Strategy
Finding the photon momentum is a straightforward application of its definition:
p
=
h
λ
. If we find the photon momentum is small, then we can assume that an electron with the same momentum will be nonrelativistic, making it easy to find its velocity and kinetic energy from the classical formulas.
Solution for Part 1
Photon momentum is given by the equation:
p
=
h
λ
.
Entering the given photon wavelength yields
p
=

Solution for Part 2
Since this momentum is indeed small, we will use the classical expression p = mv to find the velocity of an electron with this momentum. Solving for v and using the known value for the mass of an electron gives
Super-duper awesomeee video😍😍
Aaj tak hum iss dhoke mein jee rahe thai ki light has no mass😂😂
Ending ki shayari was superb😆😆
Balle Balle..Tarararara..Peace✌
I asked the same question to my physics teacher in 8th grade , and she just made a bahanna and told a speech which was completely opposite of my question.
From that day onwards since 2 years I'm searching the answer to this !😔
Thank you very much sir , meri 2 saal purani doubt to samjhane ke liye 🔥😊. !
Baal jyaada jawab the kam
Sawaal jyaada jawab the kam
Jab ghutne laga hamare dam
Jab corona aaya ya spanish flu jab the hum...
Science ne hi bachaya hame har kadamm...
Waah sir kyaa shaayri likhi aapne
😍😍😍😍awesome video...
Peace✌
1:26 I was just hearning the audio and then i thought " ok its over now, light doesnt have mass, but polar-" tab hi aa gaye Einstein bapu
4:26 amazing part 〽️〽️〽️〽️〽️
Please make the video on 'what is the Binary Language exactly?'. What exactly that meant by that 01010101010110101110 digits.
Today's video was mind-blowing.
Mind blowing session...
Balle Balle ....
Tararararara.....
Peace......
Loved the shayari very much n abhinstein uncle🤣🤣🤣🤣😂😂😂😂😂😂😂😂 harsh sir ki language me bole to "GAJAB BHAI GAJAB"😁😁😁😁
Abhishek Sir dono teacher aur dukaan daar ban sakthe hai😂😂Sach!
Ye dekh ke shock laga ke momentum ka formula itna different hota h aur hame itna easy padhaya gya and also same for E=mc². Sir please come with more advanced physics video like Quantum World and all. AT LAST PEACE ✌🏻✌🏻✌🏻☮️☮️☮️
Yes!! Eagerly waiting for this mind blowing session...
Sr apko dekhte hee dil khush ho jaata hai
And such silly vdos r really helpful
And the funny way in which u represent is really the next level
Starting me sr ko joor se lagi re...😅😅
Thankyou sir apne tho mera bachpan se bhi pehle ka doubt clear kr diya..... It was amazing😍😍😍🤩🤩🤩🤩 balle balle... Tararara... Peace 🥰
0:19 the way AKR sir addressed , reminded me of Akash Gupta ( @theskygupta ) nd his standup comedy of Sarojini Nagar !!!!! 😂😁😁
Balle balle 🤟🤟 tararara✌️ peace ☮️
Awesome video sir😍😍
shayari ki liye hats off you 🥰🥰waah waah 👏💛😂
Balle balle and tara rara😊😊🤟🤟🤟😎
Abhi Bhaiya 1.5kg light dena....or sath me thoda sa dhania & mirchi bhi daal dena..... 😂😂😂
Amazing!!! 🤩
Abhishek sir op acting lgta hain bollywood me aag lgane wale Hain💥💥
Excuse me ! Brother idhar ..reminds me of Akash Gupta 😂
Anyways the session was amazing sir 🔥
It was inspired by him only. - AKR
@@spectrumbyvedantu8283 WAH 🔥🔥SAHI BOLE ABHISHEKWA 😂😆
Sir I have a doubt that why ink pen's ink spreads on paper when water droplets falls on it, why not ball pen's ink spreads when water droplet falls on it 🤔🤔
Interesting topic of light , waiting eagerly❣️☺
Due to difference in the ink you used.
Every ink has its own property that's why they show different observations.
@@The_Tormented_One ohhh 👍
Light's weight : The untold story
Balle balle tarara 🤘
peace ✌

Mja aa gya sir
Fav part :- aditi mam ke sath wale 😂😂😂
After hearing Einstein equation and momentum equation both are not fully proper
I am like
Oo bhai ekdum se vakht badal diya jazbat badal diye Zindagi badal di
🤣Sir aap toh shopkeeper nikle😂😂🤣🤣🤣🤣
3:50 VERY TRUE!!
Woahh!! That was something interesting ✌️
BTW nice editing 😁😆
Sir you are really amazing. 💜
How can a teacher be soo intelligent and humorous at the same time😍
We want these types of videos sir ...related to. Relativity and quantum. Mexhanics
Sir, ye kuchh jyada hi heavy knowledge ho gaya. Mujhe sirf adha hi samajh ayaa😂
Sir, thanks for the heart.❤️
1:27 YE KYA THA 😲😂😆
ALBERT BABAJI 😂😆👌
I know that :- Anything with mass cant travel in speed of light
So, I thought light has no mass
Sir your name should be given for the Guinness world records for answering the most silly questions in the world.🤔🤔🤔🤔🤔🤔Guys if you agree please like the message🙏🙏🙏🙏🙏🙏.
Very informative video.... Thank you sir for your effort in taking such nice , funny and informative video....🙏🙏🙏
Super session..
Finally I got the answer.
4:27
😂😂😂😂😂😂
Being serious-But sir you are our current einstein of physics! And i appreciate your efforts as you give time for the 9th and 10th channel and even work more for spectrum by vedantu channel!🙋♀️😊
2:51 what is velovity
Sir I have a question
If we drop water it would definitely come down and we can move through an cloud like an aeroplane but why can't the water fall from clouds until it get heavier.
🥰🥰🥰🥰🥰🥰🥰
Wow never thought of this before
Lol AKR sir voices ring in my head 'Socha Nahi tho socho abhi'
Really Amazing sir
Soo Excited for the session
Sir I have suggestion for u Please make 'Time Capsule: Evolution of Light bulbs'
#BalleBalle #JaiShriHarsh #Peace #Tararara
Luv u Sir ❤️❤️❤️❤️
0:30 maybe it would be next thing which we have to buy after water and oxygen 🤔
Ohk, so for Formula of momentum, (1-v²/c²) values approximately 1 since in daily life our velocity is very small as compared to that of light and thats why we assume the formula as just (mv) 😃
Sir last shyaari toh wah wah wah maja hi aaya
Thanks a lot Sir
Peace ✌️✌️✌️✌️
Balle Balle ...........
Mujhe to tb jatka laga jab sir ne kaha ki momentum ka formula m×v nahi hai😮 and E=mc^2 equation sirf 0 velocity vaale masses ke liye hai😮. Waiting for another unknown fact 😍.
the session was soo amazing and informaive🙌🙌🙌
0:58 I`m happy light has no mass 👍👍👍
E=MC^2 ,,,, P=M*V 4:13 Dhoka...😥😥😥
ending SHAYARI was nice🔥🔥🔥
iRSHADDD
gazab.. Aaj meri dukh aur nirasha ki koi seema nhi hai😭😭 mere jeene ka koi mtlb nhi rha!!😑😑😅😅
Inspiration frm Akash Gupta 🤣😂
Sir u did it so well!!!✌️✌️..
Amazing 🌈
Thanks sir for taking such important topics and making us more informative.
✌🏻🤟🏻
Great work sir by you and your team!
💥💥
0:20 Sir, Sarojni Nagar mai ho Ft. Akash Gupta😂😂😂😂😂😂
Light has weight also
I have no idea about that
Eagerly Waiting to know!!!!! ❤️☺️
ABHISHEK SIR :- E=mc^2 KI BHI BADI FORMULA HOTI HAII!!
AUR MOMENTUM KA BHI FORMULA ALAGG!!!
ME:- IS DUNIYA MAI, SAB MOH MAYA HAI
HOSH UD GYI SIR JII!!!
BALLEBALLE...TARARARA
#NOMORESTUDENTSUICIDES
PEACE✌✌
Today I got to know tht
Momentum is not equal to mass×velocity😅
It was very informative session
And you explainee it in a very fun way!!!
Thankyou sir
Peace✌
Nice sir
I like this type of video
Sir make more video this type .
And also make long video and this type of animation.
Thanks Sir for this type of vide9
Very interesting topic..😍😍
Super Excited..waiting..😇😇
Sir I have a doubt that does our shadows exist only when light falls on us or does it exist even in dark 🤔🧐
"How much does light weigh" Waiting eagerly ❤☺
Sir is having creative 👌mindset 👌👏🙌super dooper
Wow...
Interesting...
Never thought of that..
I am curious to know now..
Balle Balle..
Amazing topic... You are osam Abishek sir Ji
I have not seen such a wonderful salesman in my whole life😂😂....sir u r the best teacher ever ever✌️
Sir my question is why do all the planets revolve around the sun ? Why aren't they in rectilinear motion ?
MIND BLOWING SIR....
I AM A NEW STUDENT OF VEDANTU
BUT U ARE MY FAVOURITE TEACHER...
THANKS....
Your acting is just amazing sirrrrrrrrr
Oh bhiru yeh toh bohotai heavy topic tha🤣🤣😅🤭 and the brother idhar of akash Gupta is the iconic one🤣🤣🤣I think sir loves it....omg what a beautiful script and editing....kudos to the whole team🥰🥰🥰🥰😊😊😊😊
Equations to bouncer gayi but maza bohot aya sir ji. Keep it up👏🏻💯🔥😎👍🏻💜
Yup sir we want another physics video like this 😊
I don't think that light weighs because if it is true then according to the particle nature, all the photons which fall on the retina of our eyes have momentum and also have force and due to which our retina would have broken but this didn't happened.
So, I don't think that light has mass.
Anyway, I would get to know the fact after watching the video.
Thanks
Amazing sir wow mind blowing.
Sir aap hamesha jo hamare school me nahi padate vahi cheez yaha lekar aate hai ❤️❤️
Just awesome like ever!!!!
Physics is easy because of some of the extraordinary persons ❤️❤️ (ABHISHEK SIR) YOU ARE AWESOME ❤️❤️❤️ (:
YES SIR ,ACHE LGTEI HAIN ,🙏🙏🙏
very good videos......sir, please give more such video
Are waah sir ji. Maja aa gaya🤩🤩
Sir you are great ....hats off to you ❤️
Damn exicted for the session.
Eagerly waiting.
Balle balle... peace ✌️
Amajjing!!!!!!!!!!!! Idk how i was able to understand this being in 8th grade
Sir ek doubt h plss dekh lo ki agar rest me body follow E=mc^2 tab ye actually E^2 = p2c2+m2c2 tha but p ka formula alag bataya apne toh kya uske according ye p2c2 pura zero ho jayega?
Wow! Interesting.
Unknown fact about light!
Thank you very much sir. Waiting for the session. 💞💞💞
Brother....iidhar ❤️❤️❤️
Amazing topic..
yhi to achha hai is channel k bare me you don't decide what we should or should not know [like schools- are ye tumhare kam ka nhi hai] ....you just tell all the facts of this magnificient universe
sir pls make a video on how air conditioner works?🙏
My mind busted out😍😚😎😉🤗🤗🤗 ! amazing session sir. 0:39 was hilarious🤣😂😆! really u are the one teacher who will be making physics easier, entertain and interesting. Hats of to you AKR SIR JI . THANK YOU SO MUCH AKR SIR AND VEDANTU.

Balle balle,tarararararara and peace✌✌
WE WANT MORE ADVANCED PHYSICS LIKE THIS SIRJI!!!!
Superb session sir,
make more videos on these kinds of topics .............
extraordinaryyyyyyyy!!!!!! session
SIR REALLY SALUTE TO U FOR PUTTING GARGARTUAN AMOUNT OF HARWORK AND DEDICATION TOWARDS LEARNING AND THANKS FOR AROUSING CURIOSITY AND FACINATION IN OUR MINDS..LOVED THE SESSION..
Sir aisa video banate hai jiske bare hum sochte nahi hai
Awesome sir 🔥🔥
Ek question mere dimag mein bhi ata tha ki why is charge of two types(+ve and -ve) and mass only of 1 type(+ve). Ye dekh ke yaad aa gaya. 😁😁If possible pls post a video on it
Mind-blowing outstanding sir
Sir please vedio on (gravity is not a force its illusions by curvature space time)
Sir its too interesting,
Curiosity is the key of science you proved.... ✌mine fav physics teacher, I attend most of your physic session of class 9 thank u 🤗
Please,take a session on mass,too.
Does your mass at 4 years is same as now ? 🤔
Video was awesome sir.😀😀☺🙂
Loved it a lot.❤❤
0:20 op🔥🔥🔥
4:17 sir 9th class mein sab cheej galat hi padhai jaati hai kya kabhi momentum ka formula toh kabhi dalton's atomic theory🤦♀️🤦♀️
Btw enjoyed the video😀😀😀
Pata nhi kyu hme sb glt formulae padhate h.. 🤣🤣 ulta sidha ans lane k liye 😒😒 jo ki koi kam k bhi nhi honge 😑😑 atyachar in student always 🤣😑🤣🤣 btw Thank you sir for letting me know THIS!!!!!!🤩🤩🤩🤩🤩❤️❤️❤️❤️❤️
