[@saviswe]

thank you very much sir for your crisp and neat explanation

[@MobiusKun]

My doubt is why we are using +f always for convex

[@ishakawade9100]

That's what, did u find the answer kyuki Kal meri board hai

[@Neetagupta1977]

@@ishakawade9100 cause f is in the direction of incident ray All those taken as +ve which is in the direction of incident ray

What happened at 3:05 ??? Couldn't understand...please clear it sir...

[@vrg6500]

Abhinav .!For concave lens focal length is -ve and for u we have to remove the distance between the convex lens and concave lens because concave lens near to the image formed

Thank u so much. I was confuse on this topic but now it clear thanks

[@aaradhyasworld1619]

Can anybody explain how object distance became +30 in case of concave lens?

[@rameshjr]

Negative + Negative = positive

[@capuneetkumar2984]

U is negative because it’s on the negative x axis ,also when you add 10 to it it becomes-30 -40+10=-30 ( negative +positive gives negative and the sign of the greater number)
