Mam can u pls tell where to mark points from scale on paper because the position of F1 and F2 are coming as yours on my scale there is gap of 5.5 and u are saying 5cm.🙏🏻 Btw loved ur way of teaching ❤
Distance from O to F2 and F2 to 2F2 should be same right? But here as per u marked it is not same so point of image formation ll not be right. Plz check mam.
Update on asked question:its better if you dont assume o to f2 and f2 to 2f2 being same. The reason being that the focal length will vary with the refractive index of the material. In case if we consider refrative index to be 2 then r=2f. With respect to the above reference the skeleton of the ray diagram is correct. We are supposed to take the aperture of lens to f2 and f2 to 2f2 to be same.
mam, what he said he correct, I'm not able to draw as per ur rule......i didn't understand ur justification also... i liked ur concave lenses video but this one was dissapointing
Am sorry to disappoint you here Pranay... I will try to find a better ratio which works for all 6 cases without a fault soon. But then again in double spherical lens the focal length doesnt obey as in a single lens case.
Mam your method of ray diagram really saved my life thanksss alot
Most welcome Kashavi. Am glad am of help to you students.
Very good explanation mam thank you so much😊
Most welcome dear.
Excellent explanation keep it up👍👍👍
Thank you so much for the appreciation .
Very easy and triky method ! Clearly all ! Thank you so much mam ! 🌷🌸🌹🌷🌸🌹🌷🌸🌹🌷🌸🌹
Most welcome.
Mam we have no words to say thankyou for this
😍😍😍😍😍😍😍😍
It's very easy trick mam very easy
Most welcome. Thank you for your kind words.
Another helpful video ❤❤❤Keep it up mam
Thank you Vinia
Thanku ma'am . Very nice teaching . And helpful

Btw loved ur way of teaching ❤
Thank you dear... And no.. u will have 5 cm.. give a try once more.. and really sorry for the late response
thanku miss very easy for your trick
Most welcome
Thank you soo much helped a lot
mam object between f1 and o is wrong?? image form beyond 2f1 but here formed at f1
Check the position in the table
Mam your name is Divine.....👌👌
Ya you are right shashwat
Guysss i have 2 preboards in a day of science:-(
Thanks a lot mamm ...it helped a lot ♥️
Most welcome Sara 🤍
Thanks mam.
Most welcome Rahman
Tq miss super teaching
Most welcome.
It is wrong. For F you should half 2 F distance. 2F was at 5.5 and F should be 2.75
Distance from O to F2 and F2 to 2F2 should be same right? But here as per u marked it is not same so point of image formation ll not be right. Plz check mam.

@@aseens ok mam 😊
Mam you are awesome
I understand this method mam👍
Am glad you found my method helpful Manish. Best of luck.
Tq mam
The ray should bend from middle position of lens. But you don't do it.
???????
Not exactly. Since it has got two refracting surfaces its goin to bend twice. But for 10th syllabus its not in depth hence the given method.
