This was the only video that pointed out that point E was not the focal point of 2nd lens, something that i was really confused about, searching everywhere for a solusion. Thank you. But now i have a new confusion, if the point E is not the focal point how is the deviation by 2nd lens (delta)2= h2/f2 mathematically valid?
Why delta2 = h2/ f2 ? .. you didn't say Why do you consider F2 as the focus of the second lens although you know that the ray incident on the second lens is not parallel to the optical axis?
Sir kya 1st principal point aur 1st Focal point ki distance equivalent focal length hogi , aur second focal plane aur second focal point ki bhi distance vo hi equivalent focal length hongi , ek jesi hongi ya alg hongi ,plzzzzz sir bta dijiye 😊😊😊
Two lenses each of focal length 20cm (first convex and second concave). An object kept at 10cm from convex lens . Calculate position of final image using the formula as given by you ????
At point P, thats because the entire deviation can be considered at that point and that new lens will focus the parallel ray at point E. But thats not even important, because the other 2 lense will be absent in the scene when you are working with the new lens😂
You write english and sometimes I hear english spoken words. But you don't speak english (or at least it's absolutely not understandable for me). Why? What language is that?

You've made a positive difference in my life
Thank you sir for your valuable lecture.
It helped me a lot during exam.
बहुत अच्छी तरह से समझाये sir ,आपका बहुत बहुत सुक्रिया।
इसके चलते मुझे अब 6 नंबर और मिल जाएगा
Thank You very much sir..
Watching from Bangladesh 🇧🇩🇧🇩
Love uu sir....
U are really amazing....
May God give u everything in ur life...
And be healthy always....❤️❤️
Tomorrow is my exam and I am going to solve this question for sure😃
Thank you sir!
I was just searching this type of vedio.
Thanks a lot
Best explanation best teacher tq sir
Your videos are very helpful for me☺️
Sir plz don't leave TH-cam
The way of ur teaching is magical bcz i can do this darivation
Itna simply samjha diye sir thanks a lot i wish your channel grow rapidly..❤️❤️
Sir! Use f2 kyo bolenge jab second lens par incident ray giri to wo principal axis ke parallel nhi thi
Very well explained. Thankyou so much😊
Why delta2 = h2/ f2 ? .. you didn't say
Why do you consider F2 as the focus of the second lens although you know that the ray incident on the second lens is not parallel to the optical axis?
No answer
Have you found the answer i am facing the same doubt
@@krushnanshjain8712 He is wrong. He just repeats what he found in other videos. They are all wrong.
Sir kya 1st principal point aur 1st Focal point ki distance equivalent focal length hogi , aur second focal plane aur second focal point ki bhi distance vo hi equivalent focal length hongi , ek jesi hongi ya alg hongi ,plzzzzz sir bta dijiye 😊😊😊
no one explain as you sir
is it also valid for concave convex and concave concave combination
Sir thick lense ki drivation ka link snd kijiye sir plzzz....ur vidos are very helpful for me ..
Sir parso exam h or aapke ek lecture se 1 topic pakka hogya😁
best explanation loved it❤👌
then wheere we will place effectie lens , in between or where
What a good way of teaching
Convex lens deviation = height / focal length. Derivation cheppandi sir please....
9:04 how sir ❓
Excellent 👍👍👍👍
Two lenses each of focal length 20cm (first convex and second concave). An object kept at 10cm from convex lens . Calculate position of final image using the formula as given by you ????
Very nice explanation
Love you sir that's helpe a lot
Thanx...I got it very well🤗👌👍👍
Thankyou sir, it's really helpful for advanced point of view ,🙏🏻
दो लेंस परिमिति दूरी पर रखने पर संयोजन तुल्य फोकस दूरी निकाले चित्र देकर समझाइए
Why del'2' = h2/f2
Good explanation
Excellent 👌 explanation
You make a nice video
very impressive
Thank you, sir
Thank you sir
Helped a lot
sir, is this formula is applicable to covex and concave combination also
What if d is getter than f1
If one is concave and second is convex the formula sir
Same formula just put f with proper sign
Thank u so much sir🤗
Agar second incident ray parallel nai hai.... . To Derivation does not make sense
Sir in which institute do you teach
Eureka institute of science
,Bikaner, Rajasthan
@@AnshuKapoor thanks sir for replying , I loved your video
Sir or video kyu delete krdi un ko upload krdo
Radhey Radhey sir
P se h1 kya hai sir please tell me sir
Principle axis se P ki height hai "h1"
Thankyou very much sir
Thank You
sir agar f2 dusre lens ka focus nhi hai to question me apne f2 ko focal length of lens 2 = 8 cm kyu kaha
Hi bahi ye jee mein ata hai kya?
Thank you sirr....!!
Good explanation.😁
sr 8*5 40 hogi 😕😕
But what will be the position of new lens????
exactly my question
At point P, thats because the entire deviation can be considered at that point and that new lens will focus the parallel ray at point E.
But thats not even important, because the other 2 lense will be absent in the scene when you are working with the new lens😂
Danyavadhagalu sir
Nice sir
Nice sir👍
Thanku sir
Kal mera exam hai or mai yeh dekhta hu sir wo raat ke 3 bje or smjh nhi aara 😂😂
Del =h/f kaise aaya
1/f=1/f1+ 1/F2
Very helpful
Sir agar apke pass optics ki pdf ho to send kijiyega...Plz .....🙂🙂
Good lecture...
👌👌👌👌
Sir ji focal length of thick lens ...ki vdo bnaiye n plss Sir mera exm bi h😓😓
Thank youuuu

Are you somewhere from Mars or what? fuckin kid
Ap sbse gande padhe hai 😢
Can you indians start doing your videos with English, not helpful 😃
It is for Indians to progress not for people like u.
Thanks a lot sir u made it easy
Excellent 👍👍👍
Thanks 😊 sir
Thank you sir
Thanku sir....
