If anyone is having doubt why we divided by 2 at last is because-
The point where u and v are same is centre of curvature and that is 2f so thats why we divide by 2.

[@kamal_ritu]

To kya saare lenses ke liye hum rough focal length ko 1.5 se multiply karke hi position set karenge??😊😊

[@experientialphysics]

Because hme lens ko f and 2f ke beech me rakhna hota he.

[@kamal_ritu]

@experientialphysics to kya object Lens ko sahi jagah rakhne ke liye rough focal length ko 1.5 se multiply ❌ karke utne hi distance pe convex lens se dur rakhna hoga??

sir iike you have taken the first object placement as 1.5 times of rought focal lenght which is 15 placed object at 35cm can i place it directly on 30? more than 1.5 times and goes down like 30-25-20-15-10 rather than going down 1cm for image readings will this method will be wrong?

Yes you can do that.
