Question

State the lens formula.

Answer 1

A common Gaussian form of thelens equation is shown below. ... If the lens equation yields a negative image distance, then the image is a virtual image on the same side of the lens as the object. If it yields a negative focal length, then the lens is a diverginglens rather than the converginglens in the illustration.
1/ v-1/u=1/ f

Answer 2

✨✔️✔️ HERE IS YOUR ANSWER....

✔️ Relationship between object distance (u), image distance (v) and the focal length (f) is referred to as lens formula.

✔ ️$\frac{1}{v} - \frac{1}{u} = \frac{1}{f}$
