Like spherical mirrors, we have lens formula for spherical lenses. The lens formula gives the relationship among distance of the object (u), distance of the image (v) and the focal length (f) of the lens. It is expressed as 1/f = 1/v â€“ 1/u

**LENS FORMULA**

Like spherical mirrors,
we have lens formula for spherical lenses. The lens formula gives the
relationship among distance of the object (u), distance of the image (v) and
the focal length (f) of the lens. It is expressed as

1/*f* = 1/*v* â€“ 1/*u*

It is applicable to both
convex and concave lenses. We need to give an at most care while solving
numerical problems related to lenses in taking proper signs of different
quantities.
