Thanks for watching the video. Most of the constants in physics are calculated by experiments like acceleration due to gravity constant is calculated by Simple pendulum method. G gravitational constant is calculated by Cavendish method
The image will be on the side of the object. It will be large and erect as shown. Remove screen and place your eye in the place of screen to see its image
Infinity means very long distance compared to the focal length of the lens so if the focal length is 10 cm a distance of 200 m can be considered as infinity
You mean height of the image. It can be roughly measured with scale on screen. Or by applying magnification formula you can calculate ua-cam.com/video/6ki0GmxoY6A/v-deo.html
In book “physics matters GCE o levels edition 4 , chap 12 , lenses , it is mentioned that object at focal point make virtual image however when I performed an experiment myself its not that way . Image formed is real.
Best explanation sir, we don't need 3 hours lectures but lifetime understanding
It is best
this is the best youtube channel for physics
Really helpful for our practical 🙏🙏 😊 thanks so much 💗 sir ji 💗🙏🙏
a perfect video to learn in a short period of time !!!!
Best teach ever ❤❤
Sir Nice video.Very Nicely explained image formed by convex lense
Thank Sir, for the detailed explanation.. Much easier to understand with a practical demo... Timely help. 🙏
You are welcome
Doing a great job for students. Good 👍
Sir your explanation is wonderful..
Sir thanks so much for the explanation , it was a lifeline for me in my practicals 😊
thank you sir you are best teacher in the world
Superb demo
Thank you it was very useful
Thank you so much sir ❤️🙂☺️. This video is very useful for me. Thank you so much.lm from Bangladesh 🇧🇩🇧🇩🇧🇩🇧🇩
You're a called teacher ❤️

Nalla avatharanam
I had easily understood Sr ...Very thanks
Best explaining thankyou sir for this vedio
Fabulously Made sir....30k soon
❤Great sir
Thank you. Now to watch again.
Best explanation sir
Saw 100s of video but didn't understand anything
Glad to hear that
outstanding experiment sir
Thank you! Cheers!
Thank u so much so informative
Bestest
Best explanation👍
Thank you 🙂
There is an error by mistake (see 0:11) 5th point. It should be "Height measured below the principle axis is Negative "
Noted with thanks
Well tried but 1.keep the object. Candle is the source of light
2. Screen should be upright perpendicular to the table
Thank u so much sir new here but understood
Very good demo
Please make more videos if possible it really helps
Tx it helped me
I enjoyed 😅
Nice video
Thank you sir
Nice sir
Thank you
Sir जब हम कोई rule पढ़ते हैं तो उसमें जो proportionality constant आता है उसकी value kese find ki jati hai

@@MakeMeScientific thank you sir
Nice
Thanks
what we have to move? lens or screen?for different readings?

please watch this
what a big and beautiful house sir i think you are rich
Not at all dear. 550sq feet 2bhk
@@MakeMeScientific sir do you work on a school
Here in the last case, the focal length was around 20 cm. What will happen if the lens is placed very closer to the screen?
Focal length always remain constant
The image will be on the side of the object. It will be large and erect as shown. Remove screen and place your eye in the place of screen to see its image
If when placed at F1 the image is at infinity then what are we seeing at the screen?
Infinity means very long distance compared to the focal length of the lens so if the focal length is 10 cm a distance of 200 m can be considered as infinity
@@MakeMeScientific but the reflected rays seems to never meet!
Kya ulta msg jane se brain pr frk pdega
Optic nerve carries signal to brain and brain converts it to straight image

How to create the screen?
Any white background can work a screen
You have to show the adjustment of the screen to get the image but not directly keeping the screen at that point
Ok
thanks for watching
Nice....wahi na....
Bhai ye 20cm convex lens kaha se kharide aur ha ye kitne ki aati hay
Amazoan se
Nice video, but sir I have one doubt that will there be image formed in lens in every case without screen??
Yes it will but to see the image screen should be placed, or else the image will be in air and cant be seen by human eye
@@MakeMeScientific thank you sir 🙏
My real question is how to measure image length :)
You mean height of the image. It can be roughly measured with scale on screen. Or by applying magnification formula you can calculate

Image of an Object at focal point should be virtual not real
Incorrect
In book “physics matters GCE o levels edition 4 , chap 12 , lenses , it is mentioned that object at focal point make virtual image however when I performed an experiment myself its not that way . Image formed is real.
If u=-10cm
F=-20cm
V=?
ACCORDING TO YOUR 1ST CASE
-6.66cm
