I think That answer of this question is wrong v=7.5
Sir in my school we have been taught lens formula as 1/f=1/u+1/v
299999 lakh
Bohot Accha Explanation tha
Sir please tell can a image be formed on left side if it is true then it is real image or virtual or negative image size or positive ? Thanks
Anyone frm 2025 batch??
Me
Anyone from 2024 boards
😢me
Yes
Yup
Me😢
Haa too
It feels like ,he is teaching from his heart ..and thus he today achieved his goal.....
Physics wallah na hota to hamara kya hota...thanks sir
Yarr hamara Nepal ma concave ka focal length positive hota has and convex ki negative 😭😭😭😭😭 how it is possible for vice versa
Focal length / power
Concave mirror: -ve / +ve
Convex mirror: +ve / -ve
Concave lens: -ve / -ve
Convex lens: +ve / +ve

Sir one day u will definately achive your goals .you will be the best teacher of physics in world .keep it up👍👍👌👌.
He already is
Haa
That has happened
Ur wish came true bro😎
You were right
Sir u r really a brilliant teacher
Thank you so much for clearing my all doubts regarding Stoichiometry.
U really deserve nobel Prize ☺
Tution chodo or padho Physicswallah se
Sahi hai...but batane ki zarurat nhi apply kar. Chuke hai
😁😁😁
Attendence lagao 2023-2024 😅😂
Focal length / power
Concave mirror: -ve / +ve
Convex mirror: +ve / -ve
Concave lens: -ve / -ve
Convex lens: +ve / +ve
Concave=-ve
Convex=+ve
Wrong
Concave mirror +ve
Convex mirror -ve
@@anupdhakal952 In concave mirror, centre of curvature lies left of pole, therefore focal point also lies left of pole, therefore focal length is negative.

No lecture can teach this concept within 10min....Physics wala sir did so..... Huge solute.... #BestPhysicsTeacher
This video cleared all my doubts that was prevailing from last few months........ I wanna thank u for preparing such an amazing video....
2024-2025 batch like

Yooo😂😂
Your passion of teaching can be detected by your actions, the way you were using your glove actually show that how much you were involved in the study
Anybody here for 2023 boards!..
Yes bruhhh
Yup
Kal hai
Yea bruhhh 😩
after 9 hrs f my science book give away
JO baccha Half-Yearly Exam main 12 Mila tha usne 90 score kiya aapki waje se sir
A big thanks to all your effort sir!!
Mere 14.5 mila ab dekhte hai board mai kya milega
Kya Mila bro?
you are the only one who make me doubt free in this chapter...i had already understood this from my teachers ..but i could not not understand this...but now this chapter is crystal clear from me.and that's only because of you alakh sir..thanku so much🤗
Sir hmare school aur tution teacher ne 1 saal me nhi samgha paye aur aap 10 min me samgha diya thnx sir
Bahut achaa vaiyaaa 🎉🎉... Bahut sare source dekhe ..nahi mila complete solution..... Physics wallah se mil geya
Thank you sir .
You made lens concept crystal clear .
😊😊🙂
The only teacher who talks on topic only. No bakwas ❤
sir ka toh jabab nahi 1 question se sab clear ho gaya
Thank you so much sir...the sign convention was always a confusing topic for me but because of you I have learnt it completely....thank you sir....😊😊
You made me regain my curiosity for the studies Sir..... great teaching 🖤
1 and a half hours before exams, you saved my marks sir haha.good luck other board exam writers !!
Sr today the recognition u get is all the results of your ingenuousness and hardwork
Hi
Sir aap phle bhi aise the or aaj bhi aise hi ho.... 🥺 never lost ur style or tallent ✌❤ god bless you alakh sir 💝
Mene apse kabi nhi padha bas name bahut suna tha per aaj radio operator ke exam k liye ray optics padha 12th ke baad se ab ..to jan gya aap itne famous kyo hue .....you really deserve it❤🫡
Thank you sir!!!
You are one of the best teacher!!
You made me love physics!!!😘😘😘👍👌👌
Sir u are amazing my all doubts are cleare now thank you sir
God bless you sir
THANK YOU SO MUCH SIR!!! YOU EXPLAIN SO THOROUGHLY. NOT LIKE OTHER CHANNELS WHERE THEY JUST SCRAPE THE CONCEPT OF THE CHAPTER THANKS ONCE AGAIN
Anybody else who is watching in 2024
Thankyou so much sir 💛
watching this masterpiece a week before my physics exams and trust me, all concepts of mine are clear now❤❤✨✨

Thank you so much😊 It helped me a lot👍
Thank you for existing alakh sir!!!❤
Thanks u so much “SIR"
Dude ur PUBGM id
Why in double inverted comma?
love you Alakh sir❤

.. u have taught such a difficult chapter in such an easy way... u really make the concepts clear... once again tx alot !!!
Nice class with crystal clear teaching...👍
Thank you so much sir....
may god bless you
Sir you are so fluent and clear .you make it easy to understand

What a amazing teacher and lecture yrr just heads of u sir a huge respect for u 👏
Sir, thank you soooo much for uploading videos. You know that organic chemistry videos are very helpful to me. Thanks:-)
I understood full concept after watching this video. Thank you sir.
You r the best teacher of world
Huge salute 2 u❤️❤️❤️❤️
How it can be possible in just 10 min...u r awesome sir🔥
U have explained this numericals in one question and when I was learning by myself I couldn't understand.... Thank u so much sir 😁😁

Excellent sir
Thank you sir it helped me to understand each and every concepts of
Lens 👍
Why r u pursing right now
you are a great teacher
mere pas koi words apki tarif karne ke liye
thanks a lot sir
Sir mast padhaya,physics ko aapse padhne ke baad pehli baar interest aaya
To remember sign convention we can use coordinates method
IV corrdinates
I coordinate -
II coordinate +
III coordinate -
IV coordinate -
What r u pursing right now
Sir aap the isi liye hi ICSE me achhe mark la paunga aaj exam hai mera ❤❤love you sir
Kitne % aaye aapke ?
Sir ji kya baat h savaaaddd he aa gya ji... Phele kuch aata nhi tha aab kuch rehta nhi h..
Zabardast sawalo ka asan bnadiya apne
Sir second formula is m=-v/u or v/u
v/u
Because Lens formula is v/u and mirror formula is -v/u.....
types of reaction kaise pta lagayee pls make viedos and tricks to find
Sir aapke wajah se hi mein apna phy aur chem ka syllabus khtm kr paya😊 ❤
Literally best teacher ever.
Sir mirror formula par bhi video bana dijiye
A vedio is already there for it
🤦♀️
9:55 CUTEST THNK U FROM AN TEACHER hehe 😂❤️
10:3*
Best one shot kind of video for revising class 10th formula application
Sir AAP se padh kar sare doubt clear hogye thank you very much
Sir you are the great teacher
You forgot one thing sir ...in the case of convex lens when object is placed between principal focus and optical centre then focal length is taken negative..
And the previous video of mirror was really very good,👌👍
sir you have cleared all doubts in one vedio you are legend🤍🤍🤍
I watching that video before 12 hrs of science pre board exam
Best science teacher in the history of world, nice explaination
Thanku
Thank you so much brother for explaining it is really very useful for me....
Sir ur such a amazing teacher all our in India best physics teacher...
Thnx very much sir
Because of u
My physics marks have incresed vry much
Thnx thnx
Sir
Plz continue to make more n more
bus yahi to aim h mera
