HOPE IT'S HELPS YOU......

Answer 2

Answer:

1/f=1/u+1/v

Explanation:

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.
