Band theory of solids | Class 12 (India) | Physics | Khan Academy 

Hey, here's a dedicated CBSE course on our website where you can practice all the concepts related to this video and more. And oh, it's always free. www.khanacademy.org/science/in-in-class-12th-physics-india/in-in-semiconductors

This explanation has made me cry tears of joy... I am so grateful for Khan Academy :)

What a clarity? You people are making learning much easier. Keep it up.

Very good illustration! The illustrator is a gifted teacher!

Loved it finally I understood what is energy bands.

and my teacher explained this in idk what language for 2 hours until my entire class slept and he finally left the class

The year is 2023 and I'm preparing for boards which btw I'll fail. It felt good to come back here and see why I had chosen science in the first place. I see exactly why I chose science and I'm grateful for teachers like u.Thank u and sorry for the drama lol

I usually don't comment in yt .. but i gotta admit ........ Best Explanation Ever.... 🎉🎉

Great sir .. No doubt remains... Perfect explanation

this was by far (for me) the best explanation of band theory... THANKYOU SO MUCH!!!!!!

Khan Academy never fails to provide brilliant videos

First time I saw someone clear this concept ... brilliant sir

Yup! I got it very well.Thanks a lot bro and keep it up!

BRO THANK YOU. I say it everytime and I'll say it again Khan Academy teachers save my life. And at the same time, I listen to them with great joy.

This makes so much sense , thanks man !!

You are so great at teaching!

I cannot thank this person enough for making it clear in the simplest manner ❤

Ahhh ,I love this explanation of bands

great .....great ......explanation. it really helped me

Absolutely the easiest explanation ! Thankyou so much sir 👍

Most beautiful explanation ever❤❤❤

This lecture help me to understand those things which our teacher 1 hour length lecture fail me to understood. Tnx💜💜💜🇧🇩🇧🇩

Wonderful lesson. Thank you, from an italian student :D

You sir deserve the greatest head ever known in the existence of man, thank you for explaining this concept in such a simple way.

Thank you 😊 Great explanation and teaching 👏

best video on band theory!!....

I must admit that I got a perfect teacher for my concepts.Thankyou so much

fantastic! thank you! free clear explanation vs my expensive uni professor difficult/foggy formal explanation. Universities need to adapt or die

I watched this in the app, and I just came here to comment that THANKYOU SOO MUCH SIR, may God bless you with health, happiness and prosperity. Best concepts and illustrations I ever saw.❤❤❤❤❤❤❤❤

absolutely loved this video! cannot thank you enough, Khan Academy

Thanks for this.. You doing a great job ❤️

Wow i learned from a lot of videos but couldn't get it till I find this video 👏

You gave such a clear concept thank you so much

Very helpful,Thank you very much

You made pauli Happy 😂.. Well Explained video

Now absolutely understand what my teacher is trying to say🙌😅😂😂😂👏gosh no one explain like this.

Heartiest gratitude ❤❤❤

You the great, keep it up bro

Yeah!!! I got it😉😉.. best explanation 👏👏 Thanks so much..

I must really thank you making me understand this topic .Thank you so much.

Thank you so much sir ,now it's totally clear what it is about

what a great explanation🔥

I amazed to these lecture

Whoa. I knew there had to be something making free electron movement happen but I didn't know it would be that pretty.

Thank you god for Indians

Wow its amazing

Perfect! I learn to the video from my material class I think it very well

Best explanation so far on RU-vid ;)

Beautiful explanation Thnx !

Thank you so much 😊 You are awesome 👌 👏

Very useful video

Woahhhh!!!! COULDN'T ASK THE CREATOR FOR A BETTER EXPLANATION 🙏

Hey, how do you know that when isolated atoms will come together and will form molecule then different atoms will have exactly increasing s,p or d orbital energy level?🤔

I got it. Thank you so much.

Thank you Excellent explanation for band theory 👏

Nice explanation sir

May i ask why you consider p orbital like s orbital with 2 energy levels? We know it is has more orbitals than s

Why unpaired electron present in 3s orbital doesn't go to bonding molecular orbital?

Crystal clear concept thank you so much

Awessssoooommmmee 😍😍😍😍

So, Pauli's Exclusion Principle is the fundamental idea about Quantum Entanglement...

made it so much easier

Thank you very much

That was so neat !

Very very awesome and crystal clear explanation 😍😍

awsome video 🥰

i got all my answers!...........you did a very good job

How much energy has each level and every band in concrete?

Now (after 7 months ) I finally understood it!

Excellent 👌👌👌👌👌

thank you from USA !!

Crystal clear explanation🥰

very nice explanation thanks and ❤️

sir there isnt a video about molecular orbital theory in the khan academy arsenal....could u make one pls

i love you bro, you made me understand shit for the first time

Very clear thank you very much sir

finally, after 22 years of my life i understand the band theory 😄

from which reference book you get this theory??

Beautifully Explained. I read ncert in half and hour and you taught me the same thing with more depth and clarity in 8 minutes wow!

WOW 😲 THAT WAS AMAZING

Excellent 👌

Loved it..love physics ❤❤

very easy explanation sir

Well explained

I have a small doubt sir, in the molecular orbital energy level diagram of Na2 molecule I see that two electrons have occupied different energy levels in 3s orbital even though there is space for the electron to be occupied in a lower energy level. Pls someone clarify me😅

Thank you sooo much sir 🙏🙏

Nicely explained

Super sir

Thank you! you are a great teacher :)

Perfect video👌

molecular orbital theory only explains covalent bonding not covalent bonding someone reply?

I got it bro.tq very much....

Why is the width of the band increasing when we will go from lower level to Higher level?

Amazing

Thank you so much sir...

Very good explanation

Thanks a lot!

thankx frm TN india

❤️

Wwoooww very nice expaination
