Answer 1

Hope it helps..

I ve given d soln

Answer 2

Answer:

The lens equation allows us to understand geometric optic in a quantitative way where 1/d0 + 1/di = 1/f. The lens equation essentially states that the magnification of the object = - distance of the image over distance of the object.

Derive lens formula v1−u1=f1 .

Derive lens formula v1−u1=f1 .From the geometry of the figure above, right angled △ ABO and △ ABO are similar. Similarly, from the geometry of the figure above, right angled △ODF2 and △BAF2 are similar. This equation is called the 'Lens formula'.
