you probably dont care but does anybody know a trick to get back into an Instagram account?? I was dumb lost my login password. I love any tips you can give me.
Thank you very much .I have searched up a lot on this topic but most of them are in hindi and i could not understand any.Finally found a worth one🙆🏻♀️
Sir, it is not clear about the sign convention you are using in the derivation (Real-is-positive or cartesian convention). For distance, height and magnification, if you are using REAL-IS-POSITIVE, VIRTUAL-IS -NEGATIVE, then Uo, Vo, Ue are all positive because they are all real, but D is negative since the final image is a virtual image.
Ue will also be negative. Moreover,the sign convention,here is pretty easy to understand. Eyepiece is just an application of simple microscope. There,we already have,1+D/fe as magnification,considering sign convention. Now,Vo is positive and Uo, naturally negative. Hence the magnification term comes in negative.
Sir I think there's mistake since 1/f=1/u+1/v then you multiple through by v then answer you get is v/u+1=v/f then v/u=m then substitute you will get m=v/f-1 that's how you will get the magnification of objective lens
One problem with this explanation is the image formed by objective lens is not the source of light! how did the light bend toward the eye piece the way in the diagram?!!
@107 Srivathsan G Actually what Ammar wrote is a correct. A and A'' would not be same even if you use the logic you presented. Either show path of A and B fully or don't use A''. This sucks in a way.
How can A' and B' be considered an ''object'' ? they are a real image. This means that A' and B' are rays of light that are allready travelling in a specific direction. Light doesen't just change direction in thin air. I have not found a single source that could explain this ''convention'' used in every explanation.
jeremy murphy , I have same problem with this diagram! Image B is not the source of light! How did he just from that image extend rays of light toward the eye piece?!

The clearest and simplest explanation.Thanks sir
What a great teacher. In this 16min I understood the whole concept
Heartful thanks for uploading in english...god bless you
I'm from kerala ✌
Me also
God bless all the TH-cam Indian teachers that have saved my college life ❤
Well explained but you forgot to put minus sign(-) in both the expressions.
you probably dont care but does anybody know a trick to get back into an Instagram account??

@Immanuel Kason Instablaster =)
It is Not kind of forgetting.
Sir simply substituted parameters. While solving numericals you can substitute with sign convention
No it doesn't matter a lot, sign conventions are made for convenience only
Aapke jaisa teacher nhi Dekha h Maine .......jhaaakash
you are an evolutionary teacher pradeep kshetrapal sir
Happy Holi sir ☺u r the best teacher in the world and u looks different from another video
thank you very much sir for your great explanation...
Thank you very much .I have searched up a lot on this topic but most of them are in hindi and i could not understand any.Finally found a worth one🙆🏻♀️
Where are u from
As i am searching a good teach as it took easy to understand in hindi
Thanq so much sir . Ap k vajah se he hmlog ka physics easy hone lga h.
Pradeep sir is my best guru
Sir you are really amazing teacher
fo should be small and fe should be large(fo
I have doubt in that
Yeah fe should be greater because the eye piece is a bigger lens than objective lens. So fe>fo.
Sir aap mahan hai🙏🙏
Sir, according to NCERT Book final image formed behind the objective lens, but you......,..
Image may be anywhere
The formed image is virtual so you can draw it anywhere in front of lens
Hello Sir I am new thanks for the teaching I do appreciate
Thanks a lot sir
Ur explanation is too good....
Excellent explanation !!!👍👍
You are great thanks sir for your explanation!!
Thankyou sir to make our learning easy
U r great Sir..aap se acha koi explain kar hi nhi sakta.....thank u sooooooooooooo much sir💕
I amThank with your lectures sir
Wow what a great explanation.
Superbb explaination Sir, cleared all doubts
I watched many videos about this
But I got satisfaction here only
In such less time.
I was confused abou L term used in NCERT Book.
Thank you so much sir ❤️
Sir, it is not clear about the sign convention you are using in the derivation (Real-is-positive or cartesian convention). For distance, height and magnification, if you are using REAL-IS-POSITIVE, VIRTUAL-IS -NEGATIVE, then Uo, Vo, Ue are all positive because they are all real, but D is negative since the final image is a virtual image.
Yeah sir plzz explain sign convention
Ue will also be negative. Moreover,the sign convention,here is pretty easy to understand. Eyepiece is just an application of simple microscope. There,we already have,1+D/fe as magnification,considering sign convention. Now,Vo is positive and Uo, naturally negative. Hence the magnification term comes in negative.
You are really an outstanding teacher who very easily clears our concepts . Thankyou very much for such a nice explanation.😊😊😊😊
Thanks for the great explanation...
Sir I think there's mistake since 1/f=1/u+1/v then you multiple through by v then answer you get is v/u+1=v/f then v/u=m then substitute you will get m=v/f-1 that's how you will get the magnification of objective lens
Hence, Angular magnification is just a name.
Thoda sign ka pta nhii chla muje...otherwise fantastic...
One problem with this explanation is the image formed by objective lens is not the source of light! how did the light bend toward the eye piece the way in the diagram?!!
@107 Srivathsan G Actually what Ammar wrote is a correct. A and A'' would not be same even if you use the logic you presented. Either show path of A and B fully or don't use A''. This sucks in a way.
his diagram is wrong
Great sir
Great sir you are legend
RIP sir...Always love you and still we miss you❤❤❤
He passed away😱??????
Ha🥺😭
😭😭😭😭
😔😢😱
Superb explanation sir thank u
Wow❤thankyou sir🙏😊
Brilliant!!!!
well explained I understood the concept. thanks
👌👍👌... wellll explained Sir...😇
Sir will it increase the visual angle formed by the object?
Thank you sir ☺️
thanks alot sir ,
But in book last image had been formed outside of focus of objective lens
Image is virtual, so it can form anywhere
@@alexanderm7575 watch Sir's lecture of this topic at his channel , he mentioned it there
if the image is being formed at infinity then what will be the value of D? should we take as infinite
D/ f
Danyabadh
Very hElpful..Thankyou😊
Why objective lens is smaller than eye👀 lens..
Really helpful thanks
Thank you very much sir,
Great. Job👏👏👏👏👏
very good explanation
Pradeep sir clear concepts .
Sir very well explain 💓n ur so cute😝
Awsm guru jii
Very good Thank you
There is minus sign in formula of mag. As u = -f not f because it is convex lens..... Check in books
Sir...But the image should form behind the objective lens only sir...
i owe you my life
nice work sir....
Thanks sir
Where did the Minus sign disappear?
Ty so much sir
It's nice
nice sir
i like ur video sir
Thank u😊
May Allah bless u sir
Osm teacher gee
Thank uuuu sir
Image by eye A''B'' is not form at focus of objective
Nice sir
Thanks sir🙏
Nice video
What happened to the -ve?
sir agar eye lens ki focal length large kar di gaae tab image for eye lens is formed before the objective lens, tab kya hoga.
please sir batao
aoa sir why we take the focal length of eyepeice lens is longer in compound microscope
Good
Sir I have a small doubt isn’t the image (final) formed at same side of the object
the rays should get refracted from convex lens of larger aperture how the rays can bend at A'
(m )e = L/fo
Where L = fo fe
To calculate L(length between two lenses) isn't it ( fo + fe)
That's for telescope
The img and the obj.are not formed at the same position so how can u use m=h'/h?
Abhinav Shukla we can always take h'/h.... we cant take the ratio of the angles if they are not in one place
Pradeep sir
Sir I think u missed out a - ve sign somewhere
negative kha gya sir
nice video #themaharajinstitute

jeremy murphy , I have same problem with this diagram! Image B is not the source of light! How did he just from that image extend rays of light toward the eye piece?!
the entire concept of ray optics is completely theoretical,infarct 85% of high school physics is only theoretical.
that`s exactly correct. Its just a real image and the diagram that sir showed is wrong.
Sir aap bahut ache lecture dete ho but vo kafi bde hote h aap km time valo ke liye bhi kuch kriye plssss
Shiksha g aap speed double karke dekh lo
I am also doing the same
Play the video 2×
super
What is D
Focal length of eyepiece is bigger or smaller as compared to objective lens....??plz someone reply...
Bigger.
Bt ncert me to cpd microscope k image k formation object k piiche ho raha h
What is a lens
Compound microscope final formula you written in this video is wrong ❌
RIP SIR 🥺🥺
Mmmmmmm much angry
Cant understand
Sir maines kaha gaya
In fact This Diagram Is not Correct...
Ran in 2x speed
