Sir i got 518 num in 9th board in physics 60/60 but in class 10th my sir stand me and ask can you explain the topic of lense but i didn't know about this topic and he ashamed me and then i watch your video
Sir is lactur ma ak jagha pa confusion ha apna phly bataya k convex lens ma principal focus negative hota ha or cancave ma positive magar book ma is k opposite ha
Sir made a mistake here Actually focal length of Convex is negative but it's power of lens is positive because focal length an is inversely proportional to power of a lens I hope you get it
Sir convex lens ka focal point tu real hai isiliye uska focal length b real hoga Similarly concave lens ka focal point virtual hai isiliye uska focal length b real hoga
Your lectures are very helpful in my study ❤️
Your method of teaching is amazing sir 👍💓
You are really amazing 💓 teacher, and your lecture is helpful in my study😎😊
Yes thanks sir
You are amazing sir. I can prepare my physics from your lectures
You are great teacher❤❤❤Allah aap ko is ka ajjar zaroor dein gain..😊
Your lectures are very helpful
I can't explain in words that how much good teacher u are ...,.....,
Thanks sir bilkul clear topic samhaj a gaya thanks 👍❤

Sir you absolutely teach outstanding i am sad that we will not study from you in 11St year😢😢
Sir you are the best teacher
I learn at once whatever i understand from ur lectures ❤
Focal length of convex is +ve
yes
Good 😇😁
😍👍
very good and helpful lecture
Sir is lactur ma ak jagha pa confusion ha apna phly bataya k convex lens ma principal focus negative hota ha or cancave ma positive magar book ma is k opposite ha
gg sir sy mistake ho gai hogi its ok
Sir aap Sy mistake ho Gai hai but it's ok 🥰🥰
The method of teaching is amazing my every concept is clear after this lecture thank u
Good
❤
You are superbbb duperbb 😘😘
Hehe..
Thank you for teaching us 😊
MashAllah 🖤
👍👍👍👍
Firstly, you ask that cocave is +ve and then you say that convex focal length is +ve.. Why??
Same question
Yes same question
Sir made a mistake here
Actually focal length of Convex is negative but it's power of lens is positive because focal length an is inversely proportional to power of a lens I hope you get it
@@imranrind9393wrong
Focal length of convex lens is positive. Focal length of concave lens is negative
Thx sir,
Amazing❤❤
thanks
thanks for you amazing lecture
greattttttttt
Sir concave lens positive hota hai aur convex lens negative hota hai sir
Amazing
❤❤
Rajab family members
Thank you

Sir aap ki 7.00 min wali baat 11.00 min wali baat say mil nahi rahi
sir g first year ka bhi phryn
I think Sir is himself confused about positive and negative focal length.
Good teaching method 👍
Well explained.. But power of lens is not cleared
sir 6:55 aur 11:25 mints p ap k statement Smjh se baahir hen plz Go saky to Saaf saaf Samjhaiye
Sir ap jo notes banaya ha is ko hum board ma liken skth ha
Sir yek question hia
Sir please clear my concept 😊😢
Assalamoalaikum sir😊
Sir convex lens ka focal point tu real hai isiliye uska focal length b real hoga
Similarly concave lens ka focal point virtual hai isiliye uska focal length b real hoga
Sorry concave lens ka focal length virtual hoga
Because real objects or things will always taken as positive and virtual objects or things or images etc are taken as negative
Sir please clear my concept 😢😊
sir ap ny ik mistake ki ha
Your lectures are very helpful
Good
