Sir can you make numerical video on each chapter . because physics is directly proportional too numerical.
Absolutely right 👍
Same bro
You are right 😁👍
Yes sir pls
But exam is directly proportional to theory
Doppler effect is deleted as per 2023-24 syllabus 👍🏻 ...(just a reminder kabhi confuse na hojao)
Ye derivations aati h kya exm me ??
Bhai ye batao sir ne kya node anti node padhaya hai kya
Hn padhaya hai@@Chemistrybloodline
Baki sirne jitna pdhaya vo sb haina syllabus me ??
@@Chemistrybloodlineyes
1:21:41 here, second harmonic frequency should be equal to 1/L√T/m .... Because early this sir told us that for n=2 ( second mode of vibration) ...lemda = L
So , in place of lemda we put L
But Sir mistakely draw third harmonic where lemda = 2L/3 so, frequency = 3/2L √ T/m
Yes

1:31:52 This is wrong, the diagram is draawn wrong, its for 4th mode of vibrtion. however the caluclation is for 3rd mode n is correct but it creates a lot of confusion. Also Pls try explaining things in a little more detail, i understand its a one shot video but its of no use if it creates more confusion than understanding, it doesnt matter even if the video had been 3hrs i wuld hv watched the whole thing if i understood things properly, but its no use i have to go see another video.
Bro same think happened to me first notes should written in videos so students can copy them and no proper explanation
Fr !!
Sir , for 2nd harmonic , it will be ( lambda= L). So it will be (frequency= 1/L √T/m) 1:22:16
yessur
Ur Chanel is really helpful for me tbh
Like I really like learning physics but somw teacher makes this subject literally soo boring and here I really found a teacher like ya !! I never get bored hearing ur lectures !

Which chapter is having the most weightage in your exams?
1:22:30 your frequency for second mode of frquency is wrong cuz lambda= L and put it 3L/2
also you have made wrong diagram in third mode of vibratiion of closed organ pipe
Exactly
Thanks buddy
1:32:49 sir this part is wrong because 1st harmonic will mean that it is only 2*(lamda/4)

Sir aapne ek mistake keeya hai. Second overtone aur first overtone ka formula galat likh deeya aapne. First overtone : frequency= 1/L√(T/m) and Second overtone: f = 3/2L√(T/m).
Initial notes mei aapne sahi se likha tha 1:21:56 . Everyone pls note. Baaki sab chiz ke liye thank you sir for helping us

Sir you are totally an amazing teacher , it's not something like buttering or making myself high ; nope . It all came from my heart ... Infact Me and my friend yesterday we were discussing about your channel 😊..
Lots of love from Kashmir sir ❤
So nice of you❤️
As-salam-alaykum bro,
Kya aap NEET ya JEE ka tayyari kar rahe ho?
Actually mai NEET aspirant hu aur abhi CLass 11 me hu. Aur Physics me mera sabse dikkat ho raha hai...bahat hi mushkil subject hai yeh. Kya ap mujhko guide kar sakta hai? If I can contact u personally or something...
sir you are best teacher of physics 🙂..i can easily understand this topics..
Thank you sir a lot !!
For completion of full physics syllabus !!
Many of us depend on your videos for physics!
True🥺
Sir Thanks a lot🎉.
I would like to say only that i can't describe u ,ur brilliance,ur hard work n way of teaching in few words...u r exceptional..love u sir❤
1:22:31 sir you have done it wrong earlier it was right
1:21:10 the written part was right here ( lemda = L)
so its the teachers problem. I gues he panicked or he didnot have his base clear.

This video is very useful for students like us.Lots of love from our side.A huge respect for your hardwork sir
At 46:45 sir its a wrong concept because if humidity increases density also increases and velocity decreases
No water molecules have very low molecular weight and prevent gas molecules from gathering together hence decreasing the density of medium
