2 years still better than others❤
now 3 yrs
Right
I just wanted a teacher to be like him
Totally agreed ✨
Bhai dp change karle ..m heartattack aa gaya mujhe

Thank you sir for great explanation
Muje bhi sir ko dekh ke rajwant sir yadd aa gaye 😂♥️♥️
😂😂😂
Your explanation is of another level sir.. u are awesome sir 😌🙏🏻🙏🏻
Galti se mene ek br physics ki koi aapki video dekh li uske bd or kisi se smjh nhi Ata 😊you are to good sir very helpful 👍
The best thing that happened to me this year was i discovered your channel. You are the best physics teacher sir 💛
Sir 2 teachers sai padh kar bii smj nhi aaa raha thaa
Thank you so much sir
Wow 👌👌👌sr ♥️♥️♥️ aap mst samajahte hai me Aapke notes purchase krunga amezon se ♥️♥️♥️♥️♥️♥️

I wish all the students of 2022-2023 batch will have 90% marks in their upcoming exams.💙
Bless and goodluck.
Take screenshot at time stamp 19:51
Thanks a lot sir.... Tomorrow is my physics pre board exam
Same me
Same me
Sir my board exam is near and your videos are really helpful.
you are luv sir ❤❤❤
amazing experience of teaching
love from kashmir ❤❤
Tq lot sir...here i cleared my point..
If we directly use lens formula expression then no need to put any condition (as you put an object at infinity & image at focus)and the answer will come easily.
Hidden gem 🔥❤️🔥
Sir we want teacher like you❣️
Sir, please make like this videos on all the chapters in you tube
Finally ..,.... I got amazing teacher of physics
Thank you soo much sir for making physics easy👍😊☺️.
U are right
Only now I truly understood
Hats off to you sir………🙏🏻🙏🏻🤩🤩
Thank you very much sir..👏🏻
You're a true legend sir 🙏🏻
Hn dear he is...😊
Class 12th Boards Students attendence here 😅😂
Sir second surface k liye R2 negative kyu ni hua vo mirror k left side mai hai
Father of physics❤️❤️
During derivation why we are not considering the sign convention
Only one best teacher that I had got in my whole 12th standerd ❤
Umesh sir is Better than alakh sir 💖 no bakwaas point to point study✨
both of them are legends i dont think it would be appropriate to compare both of them. They are best in their own way.
Right bro 😂😂😂
Both are better just shut up
Right bro
Alakh sir is best, Umesh Ji is best, everything is hell , but Science is the best
Crystal clear 👌👌👌👌
Lens maker formula and mirror formula , i will score 10/10 in my examination 😊😊😊
Best teacher in short time preparation and good time❤😊
Thank you sir for point to point explanation
Thank you so much sir for clearing this
Nice explanation sir ❤
Sir aap hmare school me padhate to ksm se sir mehh roj jaati school ...school ke teacher ke pass university ki degree to h but aata nhi padhana ...😢😢😢......thanks for this great 👍 lecture
Amazing explain thanks sir
Exllent sir bahut badiya padate ho
best physics teacher💆
In the second case of lense makers formula derivation , since the object and image both are in denser medium only , then why u taken "n1" we should consider only n2 na
Sir you explanation is awesome please bring a complete physics course either free or paid
sir ye hi 2nd surface ka concept clear nahi ho rha tha bohot dhoondha but aapne clear kr diya thnku sir❤
Such a great teacher❤❤🙏huge respect sir...
Sir maine aapni 12th physics sirf aapse pdhi thi or kl maine aapne physics ke board exam mai 56/60 score kia hai. Thank you sir thanks a lot
Sir, formula of thin lense & Lanse maker formula .....is both same or different
It's different
Mene in sir se padhkar physics me 95/100 aae the last year
Thank you sir❤
Ur my best physics teacher
Amazing explanation!
Sir lens maker formula ke derivation ki language exam mein khud bana ke likhde tho no. Tho nhi katega na ? Apki samjati hui lines se language bana ke likhe tho ?
Yes...no problem
After watching this video I fell in love with physics ❤️
you are very good explainer sir
Thank you sir
It is really helpful
Chalk and board combination is the best. No technology can match that.
Watching just before exam... And sir after studying with you I can crack board exam.. Thanks a lot to you sir
Sir, awesome👍👍 explanations thnx u so much sir
Thanku sir 🙏🙏 awesome lecture
Thank u so much sir 👍
Sir why do you take μ2 negative in second equation?
Your video is very helpful sir. Thank you🙏
Sir please make videos on a large scale tf. More and more student get the teacher they want 🙏🏻
Best explanation sir 🙏
Sir you are great
Sir what's the difference between lens formula & lens makers formula. If both are same then why we take different diagrams please reply sir i have this confusion stuck in my mind ❤
Dil se sukriya sir ji ❤️......
Thanx sir
Outstanding sir 👍
Thank you so much
Sir jo lens maker formula hota hai focal length kesmay use hota hai
Thank you so much sir ji 🙏❣️🙏
You are just awesome 🙋♀
too. good sir 🎉
You are the great sir🙏🙏
Very helpful video. Thankyou sir
Such a great concept 🎉thank you sir 🌹❤
Best teacher ever !
Amazing explanation sir
Sir aaj mera periodic test tha mai ye padh ke gya tha aapse aur same derivation aaya tha maine aapke ye method se banaya hai pr book mai thoda alag tarah se derive kiya hua hai To mai aapke method se hi banaya mujhe marks milenge na?
Yes
@@PHYSICSwithUmeshRajoria sir jaise ki apko pata hi hai ki 6th march ko physics ka board exam hai mujhe thoda sa doubt hua is topic pe mai seedha apke channel pe aagya mujhe mera hi comment mil gya 😅💗
@@gauravdey_01 bro ...am from RBSE board
.. mujhe ek doubt he.. clear kar dena plz.
CBSE ka paper blueprint ke according hi aaya kya.. ? Sure ho to btana
@@TarunJain05 bilkul nhi bhai blue print mat dekhna ahamre paas v tha par usse bilkul nhi aaya aur suno sample paper mt lena previous year le lena usse aata hai aur ek chiz ye mat sochna ki last time pe important pdh ke chale jaayenge waisa nhi hota hia suru se time waste kiye bina syllabus complete krlo
@@gauravdey_01 ye to aur tension wali baat ho gyi.. kyuki 20 ko exam h aur ab pura syllabus to hone se rha... wese mene 2-3 baar to complete revision kr liya he... but ray optics thoda reh rha h..
Abhi lens maker formula hi pdh rha tha.
Bro almost syllabus pura pdh rkha h ..lekin syllabus itna jayada vast h na ki time bhot lg rha h ek hi bar me pura revision krne m... Drr lg rha h ki kahi pdha hua bhi bhool na jaau
He was a legend 2yrs ago....now no support
Thank you for making lens maker formula derivatives video
This is so easy topic when you are taught
Love you sir 😘😘😘
