That is just sign convention if u are doing derivation just dont do this thing that if something is on left u put negative nooo its wrong we just say that its negative to clear that its on left side ❤
@@retroslayer07 sir than on what basis we select the sign convention....can you please tell me in detail that how R2 is positive sir ..I am not convinced with your answer sir
@@studypoint4115 I am not sir BTW bro just u imagine like 4 quadrants u have studied in maths like that on left x is negative and on right x is positive above the x axis positive y lies and below x axis negative axis lies just like that u remember wherever lens is given make 4 quadrants and imagine everything don't take this thing like a pressure bro that's basics just u have to remember on the left everything is negative below everything is negative and else everywhere it's positive
Sir you might have no idea how much you are helping us to make understand such a complex subject physics in such a easy and interesting way, thankyou is too less for you sir, thanks a bunch sir🙏.. because of you sir I could score 97 in physics🙏
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?
@@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 😅💗

Sir you are great . loved the way of explaining every thing ❤ now i understand everything
Sir you are a life savior for us thank you so much for your support
Yes
sir your teaching skill and drawing skill is awesome💫💫
Sir thin lens ke liye v lens formula / lens maker formula same hi hoga...??
Please reply me 🙏🙏
Thankyou sir....❤😌
Well explained
You're the GOAT of cbse physics ❤
Thank you sir ❤
Fire 🔥 🔥 🔥 brigade
Thanks sir
Thanku sir
Bohut achaa padhte hoo aap

Amazing explain thanks sir

Sir second surface k liye R2 negative kyu ni hua vo mirror k left side mai hai

But according to sign convention left of lens is negative but u took R2 positive that is my question ........
@@studypoint4115 bro listen u r just confused remember R can never be negative bro radius of anything can't be in negative
Best explition on RUclips
Better but pw is pw,😎😎😎
Good sir
Kon kon 2023-2024 bech vale hai....

sir ye hi 2nd surface ka concept clear nahi ho rha tha bohot dhoondha but aapne clear kr diya thnku sir❤
Bhai kisi insaan ki tareef karne ke liye jaruri nahi dusre insaan ki bejjati karo dono sir achha. Padate hai

2 years still better than others❤
now 3 yrs
Right
Sir please aap hamare school mein pdao
Thank sir ❤️😘💙
Sir, formula of thin lense & Lanse maker formula .....is both same or different
It's different
Thank you so much sir for clearing this
Sir, awesome👍👍 explanations thnx u so much sir
