Today is my exam😅
Meee
Legends are watching 1 day before exam😅
Here bro 😁
Jst morning before exam😎🔥😂
Bhai ye exam ka nhi practical ka h😂
@@user-vi3tn1jk8h practical exams bhi hote he bhai
Yes 😢😢
Watching it a day before my physics practical- batch 2024 ❤😂haven't studied whole year and made my concept clear in minutes..😂 All the best everyone, and to all the future buddies also ❤❤
Me also 😂😂😂😂
same :)
2 hrs before exam 🥲
Wow..! This is indeed a difficult experiment even to demonstrate virtually..

Thank you Bhavya😊
Even though I don't know hindi, you use enough english for me to understand. Thanks mate. Cheers.
Glad to hear that
we're nothing without youtube🥂
Hours before exam
Thank you sir and I needed focal length of concave lens
Thank you so much sir, this really helped me🙏
👍
Mind blowing explanation 👍🏻💯🔥
👍😊
Thank you so much, sir. I have my practical in just an hour, and this video really helped me.
Ultra pro legends are watching 1 hour before exam 😂😂
Wowwww sir I can't got a parallax method but how you define the whole sir thank you so much sir 😉 love the teaching style may god bless you❤❤❤❤❤❤❤
Thankyou 👍
Few Hours before board practical exam
Now I can say that I am also a LEGEND ❤️🔥❤️🔥
Thank u sir tomorrow is my board practical.. I have seen all experiments from ur channel only sir... So helpful 🙏🙏🙏🙏🙏
All the best
😊
Sir it would be really helpful if you could upload video for focal length of covex mirror too !! (please upload before January it would be helpful for lot of students) Thank you sir !
In college we see experiement but we can't understand but here whn u teach once we can doo it by our own. tq soo much sir ur videos helpful for us 🙏🙏🙏🙏
Cameraman op in the chat
Sir please give the video of
"To find the value of v for different values of u in case of a concave mirror and to find the focal length."
Sir please my practical is in 5 days.
Wow sir kya explain kiya, best explanation.
Thank you😊
Thank you sir today is my practical it will surely going to help
Definately. All the best 👍
This was the best explaination ever 🙏🙏 I appreciate you sir , I understand better with your explaination than in offline mode of my school experiment 🙏🙏 So thank you so much .
👍
Thank you very much sir
👍
What a explaination😍
Thank so much sir thank you 😊thank god muja experiment samaj aa he gaya
Thank a lot sir Tommorow is my board pratical and this type of videos mean a lot ❤
Goodluck 👍
Watching practical before two days 😁😁
Sir you explain this experiment so easily thankyou so much sir for your efforts ❤️
Right comrade
thank you sir🙏🏼 all your videos are really very helpful 💖i have my prac tomorrow need your blessings sir😊

Most amazing channel ever found
You're going to gain fame soonnn...
Thank you😊
bhai 2012 se channel hai fame kab aayega
All the best for your tomorrow practical exam
Thank you so much sir🙏
This was the best explanation of the experiment so far in RUclips
👍
Best materiel on youtube
Monday ko practical hai kya
And kitne aye physics mein
Thank you 👍
@@logambikasworld975 yes bro mera h aaj
Thankyou sir
For this amazing explanation
Tomorrow is my pratical
super explanation pls do all cbse experiments
All experiments are there on channel. Thanks
thnaks sir, kuch hi ghanton mein practical hai. this video is best.
UNBELIEVABLE😘😘😘😘😘😘😘
Leaving this comment here as tomorrow's my physics practical so if anyone wanna know how it went can ask me 😊
Kesa gya
@@sxndhujatt pretty good actually we didn't even need to perform the practical, it's all just a formality mate
@@priyanshuchoudhary35 same😂
@@sxndhujatt hope the same for the chemistry practical 🤞
Sir thank u so much this will really help in my class 12 th practicals
Glad to hear that
Thank you sir 😊 😊
2022-2023 🤣
Best of luck bro
If anyone is having doubt why we divided by 2 at last is because-
The point where u and v are same is centre of curvature and that is 2f so thats why we divide by 2.
Very helpful video sir ji 😃❤
👍
Tommorow practical exam❤❤
Thank u sir for make our practical exams very easy and also to make more interest in physics subject ❤❤❤❤ thank u so much sir.
👍
That autofocus is testing my patience
Thank you sir 😊😊
Thank you for your effort sir I am giving practical exam tomorrow. It is Very helpful for us. Sir please add Procedure in The Description sir
Good luck 👍 and in practical exam you need not write down procedure. It's just you have to perform.
Thanks a lot for the tutorial. I was daamn frustrated as I don't get anything in school
bhut bhut dhanyawad aapko🙏🙏
best way of explanation
Sir can you please make a video on " To find the focal length of a convex mirror using a convex lens"
Sir can u make video on the experiment
"To find focal length of a concave lens using a convex lens".
Its my request. Pls make it before Monday. Monday is my physics practical exam🙏🏻🙏🏻🙏🏻
Ok will try
😊
Thanks sir
upload in better quality 360p is very blur
it's very helpful sir, kindly try to cover even more errors and difficulties
Thank you so much sir
Thank to clear the concept..😊

It is very helpful thanks
Thank you so much sir per hamare focal length of concave mirror bhi hua hai per apne vedio nehin dale hai ese bhi ek vedio banaye sir plz
Thank you sir 😊
Sir aapne knitting needle ki measurement kyoo nahi li??
Uski jarurat nhi he lens thin he to
@@experientialphysics ok. Thank you sir 😄
I'm. Watching before 1 hour before exam 😂😂😂
Crystal clear concept ❤️
👍
Sir Quality video increase karo 360p pe khatam
Very nice explanation
Intro jordaar tha
Dhannebad guruji
Vry gud explained sir ❤👌🏻👌🏻
Sir do we have to multipy the rough focal length by 1.5 times. Just want to confirm.
Yes because you are placing object between f and 2f and image obtained beyond 2f. That what we are doing in this experiment to obtain correct focal length.👍
Thank you so much🥰
