In comments ki wajah se sir un comments ko nahi padh paate jo actually bahut zaroori hain... So i request to all of u ki comments mein sirf doubts aur important information hi share kare🙆♀🙆♀🙆♀🙆♀🙏🙏🙏
Hello Sir, this is the first time ever.. I'm commenting.., I'm really amazed with the way you teach, I always wanted to tell you how amazing you are.. but never had my own channel to do so!

Even we feel connected to you sir, really not just saying. Jab mujhe sach me koi point samajh me nai aata hai usi time aap keh dete hain "Nai aayaa samajh? Ye dekho dobara". If this is not connection, then I don't know what is.💓🙏🏻 I lack words to express your hardwork, dedication and honesty towards your work.👑 Teacher like you is the dream of every student out there!
Just one thing to say sir, just keep loving Physics! You're doing for this nation..... Mai toh keh rha hun sir election mein khade ho jao pakka jeet jaoge! Itna selfless work toh koi Neta bhi nhi karta😁
Almost 2 Million 💯💯thanks for sharing exact concepts with visualization of we kids subjects which majority of us used to fear from but not anymore because of Physicswallah! 😊
It completely feels like as if you are sitting in any coaching institute or any classroom when you are watching Alakh Sir's lectures inspite of being at home.

I studied microscope from more than 3 teachers and to tell you all, only Alakh sir has the capability to explain to the level ki sab clearly samajh aaye... Jab koi topic samajh na aaye physics mein, kahin jaane ki zarurat nahi... Just open TH-cam and search Alakh Pandey with the topic name.... aisa kuch hai hi nahi jo aap samajh na payein when he teaches❤️❤️

Wow....the best Ray optic lecture I have got in my life...what a detailed explanation....just love you sir ❤❤
Even we feel connected to you sir, really not just saying. Jab mujhe sach me koi point samajh me nai aata hai usi time aap keh dete hain "Nai aayaa samajh? Ye dekho dobara". If this is not connection, then I don't know what is.💓🙏🏻
I lack words to express your hardwork, dedication and honesty towards your work.👑
Teacher like you is the dream of every student out there!

Sir ,you are really working very hard for us .Thank u sir for this amazing, awesome ,beautiful vdo . Again thanks a lot sir........
Thank you sir for making this video it,s really help it
I studied microscope from more than 3 teachers and to tell you all, only Alakh sir has the capability to explain to the level ki sab clearly samajh aaye... Jab koi topic samajh na aaye physics mein, kahin jaane ki zarurat nahi... Just open TH-cam and search Alakh Pandey with the topic name.... aisa kuch hai hi nahi jo aap samajh na payein when he teaches❤️❤️
Another masterpiece by alakh sir
It's too good.......
Really appreciate you😃😃
Yes 😊
All my 11th 12th are these videos these are the memories and everything ❤
