It would be independent of the setup ig as the angle substended by the obj on the lens wrt principal axis would be same irrespective of where you keep the new lens from the object. Also see that if in q.. Distance is given wrt O1 lens.. Ig u can take it for the combined lens too.. As angle substended by the object doesnot depend on the height of the lens

Ig it will.. Just first calculate the resulatant focal length of 2 lenses (f12) and then the resultant focal length of f12 and f3 by the same formula.. Just apply the formula two times..

How does the distance f2 in the drawing represent the focal length of the second lens? .. this is not correct. It can be correct only if the incident ray is parallel to the optical axis. This is not the case for the second lens.
@@kamaldheeriya Incorrect. Listen to me, the point F2 is not the focus of the second lens but the focus of the system as a whole.. Many Indian videos on youtube do this bad mistake.

Superb without deviation deviation is derived for both the cases. thanks a lot.

But what will be the position of new lens with effectiv focal length
It would be independent of the original setup

Will it be applicable for all the cases? F1 and F2 will be placed with sign or not. In one case i find some difficulty with this formula.
Use sign convection acc to lens

What will be formula for 3 lenses, will this work. Sir please tell 🥺🥺

I can not understand how u find out value of BETA = h2/f2
This is the approximation
Ooops
But what I have told about that F2 is focal length of second lens assuming the Ray refracted from lens 1 is parallel to principal axis
All derivation of ray optics are is for small angles
@@kamaldheeriya 🆗 thank u

R u out of yr mind, see the diagram clearly, one has more focal length and other has less compared to the first one

@蕭宇辰 Thanks!
Ya I think you are right. F2 is of whole system.
Derivations in indian books = kuch bhi krke formula la do 😏
My doubt is that what is the position of equivalent lens.. in d
Separated by d condition? Pls reply
Just u need only seperation between the two lens
@@kamaldheeriya and the distance between the object and equivalent new lens?
What is the need for that, just find their equivalents focal length and than use lens formula
@@kamaldheeriya yes sir but while using lens formula what will be "u" sir?
@@kamaldheeriya sir pls reply
dont you have any pity for student ??? why after every minutes there is an ad??
I have not set it, it is by default
@@kamaldheeriya no it's not by default.
@@kamaldheeriya one can manage it how many adds to put.
its business dear
lol>>>>
who teaches in free of cost for you
Best explanation thanks sir
