Best explanation sir, we don't need 3 hours lectures but lifetime understanding
It is best
Thank Sir, for the detailed explanation.. Much easier to understand with a practical demo... Timely help. 🙏
You are welcome
Really helpful for our practical 🙏🙏 😊 thanks so much 💗 sir ji 💗🙏🙏
this is the best youtube channel for physics
a perfect video to learn in a short period of time !!!!
What a great effort, Best explanation,more power to you🌹
Thanks a lot 😊
Doing a great job for students. Good 👍
Sir Nice video.Very Nicely explained image formed by convex lense
Best teach ever ❤❤
Thank you so much sir ❤️🙂☺️. This video is very useful for me. Thank you so much.lm from Bangladesh 🇧🇩🇧🇩🇧🇩🇧🇩
This video was very helpful!! Thankyou so much.
Sir thanks so much for the explanation , it was a lifeline for me in my practicals 😊
Superb demo
Thank you it was very useful
thank you sir you are best teacher in the world
You're a called teacher ❤️
Thank you so much sir this help me a lot ☺️ for my exams 📚📖👌👍👍
Best explanation sir
Saw 100s of video but didn't understand anything
Glad to hear that
Fabulously Made sir....30k soon
I had easily understood Sr ...Very thanks
Sir जब हम कोई rule पढ़ते हैं तो उसमें जो proportionality constant आता है उसकी value kese find ki jati hai
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
@@MakeMeScientific thank you sir
Wow great explanation 🙂🙂
❤Great sir
Nalla avatharanam
Thank you. Now to watch again.
Bestest
Thank u so much so informative
what we have to move? lens or screen?for different readings?

please watch this
Please make more videos if possible it really helps
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
Well tried but 1.keep the object. Candle is the source of light
2. Screen should be upright perpendicular to the table
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....
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
Thank u so much sir new here but understood
Kya ulta msg jane se brain pr frk pdega
Optic nerve carries signal to brain and brain converts it to straight image
Tx it helped me
outstanding experiment sir
Thank you! Cheers!
Sir your explanation is wonderful..
Very good demo
Thank you sir
Thank you
I enjoyed 😅
Nice video
Nice sir
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
Op
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
ua-cam.com/video/6ki0GmxoY6A/v-deo.html
If u=-10cm
F=-20cm
V=?
ACCORDING TO YOUR 1ST CASE
-6.66cm
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 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!
Best explaining thankyou sir for this vedio
Bhai ye 20cm convex lens kaha se kharide aur ha ye kitne ki aati hay
Amazoan se
Nice
Thanks
Best explanation👍
Thank you 🙂
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 🙏
