Hello sir. Firstly thank you so much 😊 for providing such good quality video lectures through a platform which is easily accessible to everyone. I’m a jee aspirant and I’m in 11th. In the initial days of my jee Physics lectures I couldn’t understand anything and didn’t have affinity towards physics at all. But then when I started watching your videos things changed drastically and I improved a lot. You are doing a great job you are the best physics teacher ever I have seen in my life. Keep uploading such videos and sir please finish the whole jee syllabus before 2021 because this is when I’m going to give my jee exam. I’m dependent on you for physics as I don’t understand completely what my physics coaching teacher teaches in class. And sir a very humble request please please increase the frequency of video lectures of physics.

Bhai nov mid tak bohot mushkil hai. Sir videos kam daal rahe hain to matlab kuchh to problem hai. Waise sir ne december tak bola hai karwa denge. Tension na le. Ho jaayega
Exactly same problem which I have faced right now. I got confused between n1 and n2 ,as alakh sir techaed us in real depth and apperant depth. Then I start looking at the comment section, & I finally found you.
@@ranjanmohanty4877 only that friend who does not agree with your point everytime is the real one. That friend will always depict a real image of you..
Sir jab hmne real depth and apparent depth padha tab we took n2 jisse light aari n vice versa but now in spherical surface refraction different,does this depend on derivation ,what we take during derivation? I hope u will answer.
I'm really thankful to being born in this Era, the Era of internet revolution and where people are given freedom and infinite possibilities to learn what they like. And I thank LEGENDS like Alakh sir who are providing WORLD-CLASS Education on a platform like RUclips. PS- A student from Udaan 2025
Moreover sir.. There are student's like me who comes frm state like arunachal pradesh... Here tution coaching aren't that available.. All what we hv is our institutions n ur teachings.. 🙏🙏🙏🙏
This session us very helpful... Maine puri utube chaan li pr mujhe ye concept smjh hi nhii aa rha tha.....now the whole concept is crystal clear to me.....thank u thank you thank you so muchh sir.....u r a true legend..
sir real depth and apparent depth men bole the n2- jisse light aa rahi he. now n1-jisse light aa rahi he..It will make me little confusion further, I guess. Anyway, thanks sir for your effort.
the best way to remember it is that wherever your eyes are that'll be n1 , this is for the apparent depth case and so the opposite for the spherical surface
You are very knowledgeable Sir. Thank you so much for explaining everything so clearly. I'm very comfortable with this topic after watching your video. My best wishes to you Sir. :) :) :)
At 1:17:40 sir agar hm logon n mirror 2sri wali side ko mana h to distance bhi 2sre pole se hi na li jayegi to jo object ki distance h vo -5 honi chahiye na +5 ki jgh
@Arpit Gupta Lekin Sir Ne Mirror matlab (Refracting surface) left se hain na aur observer right main toh barabar hain because eye is given in the question itself
At 1:16:51 , sir made a mistake If i1 is a virtual object then rays will start from it u= -5cm and R= + 5cm so that we get v= - 5 cm *Final image is formed at centre and is virtual* _(Plz correct me if I'm wrong ...)_ 🙌🏻❣️❣️❣️
Only bcz of alakh sir I developed interest in physics 💖thanks alot for your efforts in making these videos and makes us the topic crystal clear Lots of love for you sir from the whole physics family of ur channel 💖❤️may god bless u with good health, more and more success in ur life 😊 and a long life full of happiness
When sir starts singing😆😆😆 not only me, but also my family memebers enjoys it soo much. Yesterday my mom started singing when i was listening alakh sir's magnetic ef...Video, there he sang " ik pal ka jeena". 😆🤭
In question find the position and nature of image, can we apply that convex lens are converging lens therefore img is real and concave lens is diverging lens therefore img is virtual
Sir, I woke up at 4AM today... and guess what, I was super hyped to continue watching this series. Although I am not going to appear for JEE/NEET solving questions of the 'JEE/JEE.ADV' level is pushing me out of my comfort zone which in turn helps my logical faculty to grow exponentially, and I am pretty sure that I will be able to pass 12th grade with flying colours XD Thanks a lot for the efforts you put into these videos : )
Sir, literally earlier I was sooo that confused ki I was totally frustrated about the sign conventions and other things used in this formula.. But now, my all confusions and doubts are crystalll clearrr..✨🔮💎 I m soooooo happyyy! Thank you So so much sirr..! ❤

so,agar waise yaad rakhna hai...so can we replace n2 by n1 and n1 by n2 in the formula... usse bhi aa rha h...as wo to sirf ek notation hai...
Exactly same problem which I have faced right now. I got confused between n1 and n2 ,as alakh sir techaed us in real depth and apperant depth.

n2/n1 = d/d' where n2 is R.I( refractive index) jidhar se light aa rhi hai and n1 R.I of medium jidhar ko light jaa rahi hai.
So what is the solution to this problem? Please help

Sir:- let us take this as YUM
Really very happy to have 3 million students family...... We Love u physicswallah sir 💜💜
9.53m now
Moreover sir.. There are student's like me who comes frm state like arunachal pradesh... Here tution coaching aren't that available.. All what we hv is our institutions n ur teachings.. 🙏🙏🙏🙏
This session us very helpful... Maine puri utube chaan li pr mujhe ye concept smjh hi nhii aa rha tha.....now the whole concept is crystal clear to me.....thank u thank you thank you so muchh sir.....u r a true legend..
Ho gya syllabus complete ?😂
54:53 when sir saying - 22.5 at that time if you tap on time, the remaining time will show exact answer -22.50 😱

sir real depth and apparent depth men bole the n2- jisse light aa rahi he. now n1-jisse light aa rahi he..It will make me little confusion further, I guess. Anyway, thanks sir for your effort.
Right

Sir pehle ray optics bilkul samaj nahin aata tha, par aapse padhne ke baad voh mera favourite topic ban gaya hai sir.
Thank you so much sir.
the best way to remember it is that wherever your eyes are that'll be n1 , this is for the apparent depth case and so the opposite for the spherical surface
most brilliant teacher of the era- Mr. Alakh Pandey sir
I just love physics sir bas apki wazase. Thank you so much
Sir, Hats off to you for such a great work.......
Thanks sir
During my exams you are really helpful and supporting to me
Really sir thank you so much for such a good teaching......you are tooo good👍👍👍😊......please keep helping and supporting students like this forever👍
Sir physics is a magical number agr smj a gya to mst ha vrna to magic ho jata ha........... 🙃🙃😄😄😄🤟🤟🤟
point to be noted "jahan do rays milti hai wahan pyar ho jata hain 5:29"
1:14:32 only legends knows
jaha se ray arahahe vo n1 hon chahye matlab object air me
so n1=1 hona chahiye
dono case me bhi answer same ayega
yes bro appne sahi kaha sir ne wrong le liya hai syd
You are very knowledgeable Sir. Thank you so much for explaining everything so clearly. I'm very comfortable with this topic after watching your video. My best wishes to you Sir. :) :) :)
Gzb...sir ke natural voice effects +his killer expressions.....
😂😎
At 1:17:40 sir agar hm logon n mirror 2sri wali side ko mana h to distance bhi 2sre pole se hi na li jayegi to jo object ki distance h vo -5 honi chahiye na +5 ki jgh
Ma bhi yhi soch rha hu Yr.. .
yes ... i think sir made a mistake
Yes i also have the same doubt...😥
Ans is coming same don’t worry u=-5,r=5,v=-2.5 same
@Arpit Gupta Lekin Sir Ne Mirror matlab (Refracting surface) left se hain na aur observer right main toh barabar hain because eye is given in the question itself
Kitna pyar say aap padhata ho Sir.
Sir Aaj iss shirt me bohot dope lag rahe hai.....😍😍
while deriving the formula, we already considered "u" to be negative but then again, while solving problems, we took "u" as negative. Why is that?
Best teacher for phisic any sunject
At 1:16:51 , sir made a mistake
If i1 is a virtual object then rays will start from it u= -5cm and R= + 5cm so that we get v= - 5 cm
*Final image is formed at centre and is virtual*
_(Plz correct me if I'm wrong ...)_
🙌🏻❣️❣️❣️
but then also we get the same answer bro just check it again at once
Sir doubt in Q3
For refraction from denser to rarer medium we are give the following formula
N1/v - N2/u =(N1 - N2)/R
N1 is from where ray is originate .....N2 is where the ray finally goes...so N1 is glass and N2 is air
Yeah i had also same doubt
Beautiful video :) you're our strength. Diwali wishes in advance sir. :)
Same to u ,happy diwali in advance

Who is doing this lecture for 2024 board exams .love your all lecture
Board ne pattern change kr diya pr humne aaj bhi vhi pattern rkha hai sir se padh ne ka
Thank you sir
i am watching for these videos for gb paut examination and boards, these lectures are very useful for our future
Only bcz of alakh sir I developed interest in physics 💖thanks alot for your efforts in making these videos and makes us the topic crystal clear
Lots of love for you sir from the whole physics family of ur channel 💖❤️may god bless u with good health, more and more success in ur life 😊 and a long life full of happiness
Hello bachoo is directly proportional to physics feel , and constant is babita ji
Smh
Welcome back sir
Aapka new video dekhke dil khus ho gaya, fuli nahi sama Rahi
Very very very happy.
Ghabrat band ho gayi
When sir starts singing😆😆😆 not only me, but also my family memebers enjoys it soo much. Yesterday my mom started singing when i was listening alakh sir's magnetic ef...Video, there he sang " ik pal ka jeena". 😆🤭
If you were my college's instructor, sir, we could even do well on India's competitive exams.Much appreciation from Nepal
Ok I am watching this here rn after 5 days my Physics board is there and I will update you how was the exam.Let's get it
How is your exam
It is just wowsome.......Thanks sir for supporting us........ Concepts Clear....... Keep it up..... 🙂🙂🙂
Yes this absolutely true for physics wallah he is very. talented teacher of all other
Thanks a lot sir. U r truly a bharat Ratna. Love you sir. Thanks for helping me so much during these 2 years
In question find the position and nature of image, can we apply that convex lens are converging lens therefore img is real and concave lens is diverging lens therefore img is virtual
Sir pura concept clear ho gya . Thanku so much sir😊😊😊😊😊😊😊😊😊😊😊
Fielding mein Manish pandey aur physics me Alakh Pandey ko koi bhi beat nhi kr sakta h... 🙏🙏🙏🙏🙏

Sir aapke videos dekhkar dil or dimag ke sath fefde bhi khush ho jate thank you sir for videos ......
😍😍 physics wallah lovers like thoko😍😍😍
Sir, I woke up at 4AM today... and guess what, I was super hyped to continue watching this series. Although I am not going to appear for JEE/NEET solving questions of the 'JEE/JEE.ADV' level is pushing me out of my comfort zone which in turn helps my logical faculty to grow exponentially, and I am pretty sure that I will be able to pass 12th grade with flying colours XD
Thanks a lot for the efforts you put into these videos : )
GOOD ENGLISH BRO!!!!!
Kid trynna solve JEE Advanced problems and says he's not gonna appear for JEE😂
Kitne no. Aaye ? Flying colours!!
@@ANANTGARGIIT-D I think u r in 12th ?😅
toh de hi de na JEE...
sir because of u i hv gained confidence in physics..so far so good because of you..thank you so much
Sir u are really amazing I am fan of the feel of every topic which u give really proud of u sir
Lecture starts at 19:34
Sir iske baad modern physics start krna please sir
It's a request 🙏🙏
Sir, literally earlier I was sooo that confused ki I was totally frustrated about the sign conventions and other things used in this formula..
But now, my all confusions and doubts are crystalll clearrr..✨🔮💎
I m soooooo happyyy!
Thank you So so much sirr..! ❤
Hellooooo sir to aj mai padhne aai hu refraction from spherical surface.. so my name is arzoo and this is our cute sa channel physics wallah
