Physics Wallah - Alakh Pandey
congratulations sir for 2M
Sir or videos kb aaengi waves ki?
Thank you sir for making physics way more easier and interesting for me

I can't imagine my education without physics wallah...... Tq sir...
Yess me too
Brother , you are too depends on physics walla. That's not ok.
@@rajibsamanta3693 whyyyy why why why why why whyw hwy why w2hwy
Yeah. Of course me too
Same here
I m studying at allen.. the only difference that I observed btw alakh sir and allen faculty is that sir has better skills to make u feel the topic.. that was lacking in coaching..
Same!
Sir is better but allen is great too. :)
I'm an Aakashian too. But I feel the same. Alakh sir's vibes are something totally different. Thank you sir
In which state
Same..!
When he said no one cares weather you lives or not 😭i really felt that . True
Whether dude
everyone cares until u r beautiful rich or famous.

@@ayushkumar-bs8ng you should write -NO ONE cares until you're beautiful , rich or famous
I can't imagine my education without physics wallah coz my physics knowledge was like deuterium's existence in nature bt now physics exist in my each drop of blood,ur lectures r in such a way that bhulkar bhi bhule nahi jate............Thank u so much ALAKH PANDE sir for physics lectures in easiest way
@Chad I can feel bro....༎ຶ‿༎ຶ
Deturium reference was so random

i m shocked to see that my aakash teacher gives same questions as given by respected alakh sir...
O My God
even my teachers bruuh, everyone has got their source of knowledge from here
I wonder how come a person be such TALENTED! I'm from USA, majoring in Mechanical Engg. You are wayyyyyyyyyyy better than the USA professors. You deserve my tuition fees instead of them. Now I skip my physics class, cause I know I have physics wallah! I was panicking for sooo long cause I don't understand the lecture in class, and then I found you. Water in my desert!
I must say not all heroes wear capes. YOU THE BEST
Razia Sultana Shushanta stop lying sweetie

Sir hame toh physicswallah naam padhte hi like karne ki aadat lag gai h .... and video complete karne ke baad afsos hota h ki kaash per person more than 2 likes ka option hota 😊😀😂.... love you sir we are really admired to you
Ooh my god...he is called the ◇golden legend...he is solid gold
Sir how I wished that I could get you as my school or tuition teacher. Live in front! You are just amazing. You make us understand the concepts than just read the book. Great respect for you sir!!
Hm gadhe hi hai SIR..... but aapki wajah se 😝😛😝update ho rhe....EVOLUTION hoga jld🤣😂❤❤❤❤❤❤

Hello sir , thank you sooo much sir. U R best teacher in the world, I was eagerly waiting for this lesson.
Love you too ,sir ki side se.
Sir at 20:45 ynet equation should have kx1 because sir A1 is having initial phase of kx1 which means Anet should be
Ynet=Anet sin(wt+kx1+thetha)
Correct me if anyone see my comment
same confusion bro
