Question

state the lens formula​

Answer 1

According to the convex lens equation, the lens formula is 1/f = 1/v + 1/u. It relates the focal length of a lens with the distance of an object which is placed in front of it and the image formed of that object.

Answer 2

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.
