But in my house every morning i am wished by my parents " hello bachhoooo" and they also sing songs while u sing...
U r the best teacher sir....
Thank you.. those who liked the comment
I've never commented on any of your videos. But, today I sincerely wanna thank you for your insane dedication towards teaching u legitimately explain every topic in a marvelous way that it gets set inside mind. I was never a "studious" kinda student and even if I try to study and try to solve the numericals I couldn't. Sometimes I used to leave them by looking at the length of question. But today I can actually solve many questions. I ain't saying I can solve every question out there but yeah, I've improved a lot in physics. Heartily thankful of you sir 🥺🖤
Me two 🥺
Issey axa to mat hi cmmnt kr bhai😶😶
Sir kbhi kbhi sochta hu agr aap nhi hote toh ky hota ,Aisa sochne p bhi man kharab ho jata .Sir apki ye videos na sirf humare seniors , hme , or humare aane wale pta nhi kitne juniors ko serve krne wali hae. A very big thank you from all your pyaare baccho❤️

मेरे जैसे हिंदी मीडियम वाले बच्चे 1:02:55 पर प्रतिबिंब सुनकर बहुत खुश हुए होंगे(दो साल बाद हिंदी वर्ड सुना है हमने physics में, वरना हम तो भूल ही गए थे कि sir english medium के लिए पढ़ाते हैं पर sir ने कभी फील ही नही होने दिया कि हमारा मीडियम अलग हैं )😀
अब तो मेरी क्लास के बच्चे कहते है की तू पहले इंग्लिश मीडियम में पढ़ता था क्या जो फिजिक्स इतनी आसानी से समझ आती है तुझे, और वो भी इंग्लिश में 😊
after watching a lot of new vdos.. coming back here b like.. sr aapke looks change ho gye hn thode... backboard.. shirt... marker... duster.. sb badal gya... the thing that's still constant is the way of teaching... kutuk.. is constant.. your beta is constant... in the end.. physics constants are also constant... just like you... hope I could meet uh once... at least once in a lifetime...🙂
✌
Arey " Hello bechho " Is also constant... Alakh sir is love....

This was the first video which i saw of physicswallah almost more than a year ago..and this is my first comment...
शुक्रिया sir..you made my neet preparation a lot easier❤️
yes sir optical fibres are in the form of video and audio
video:- in our tv HDMI cables (high definition multimedia interference)
audio:- we have optical cables in our sound receivers which gives us 5.1 or 7.1 or Dolby Atmos surround sound
sir, you are really a great person we are blessed to have a teacher like you sir.thank you very much sir for explaining this topic in such an easy way.i will be always thankful to you sir
Sir your efforts are speechless
Thnx for being in our life

Just a small correction at 1:06:30- Normal broadband connections are made up of twisted pair cables , optical fibres are usually used to transfer data from continents to continents or within country. ISP's provide a lower quality optical fibre at cheaper rates which are now in frequent use but they are optional....the wires in lan port are of copper and not of fibre
It is used in broadband ...
Amazing, Amazing, Amazing, Amazing, Amazing, Amazing, Amazing Sirrrrrrr. Today I am regretting why I have not seen your videos before....... I think it's too late for me. But still I will try my best....... Lots of respect and love Sir 💗

I don't know if anyone else has noticed it but in last lecture sir said that he would change the board and in this video he actually did that. Sir ka kaam speed of light ke itna fast aur punctual hai.
I REALLY DON'T WANT ANY LIKES IN MY COMMENT BUT IT'S TRUE THAT IT IS MY FIRST COMMENT IN ANY VIDEO... BASICALLY I FEEL VERY PROUD TO COMMENT ON VIDEO WHICH IS TAUGHT BY ALAKH SIR...
