Trust me merre all dosto preboards aren't tough , merra aaj science ka tha preboard aur paper wasn't tough it was soo easy , agar jisne akr sir , ag ma'am aur Amrit sir se phada hoga , for sure all paper which you will be giving will definitely look easiest 😌😌🔥🔥
Sirrrr please do sessions for ICSE students tooo ! We are too very afraid of upcoming board examination and seeing so much cbse stuff make us feel that we should also gets some supervision !! Sirrr my humble request to provide live sessions for ICSE students too 💙✨

Hi
Sir
Once check the refractive index topic
n12=n1/n2 is wrong
n12=n2/n1 is correct
Please check please
I'm not discouraging 😃
Ye apne bahut achi bat kahi hai Maine misunderstand kr lia tha muje doubt bhi tha pr apne clear kr dia thank you
Nah man he's right
Cuz only when u compare the speeds of the 2 objects, n12=v2/v1
In case of refractive indices its n1/n2 only
Hope this helps 😁
@@adnaan9419 Yea you are right man
Isn't this series among the best we can every find on TH-cam? Hats off to Abhishek Sir and the team behind it...!
Yo watching it before a class test in the starting of 10th 😄

A mistake done by vedantu is convex mirrior is converge whereas concave is to diverge .
