Lensmaker's equation:
1/f = (n1/nm-1) * (1/r1-1/r2)
Where,
n1 -Refractive Index of Lens Material
nm -Refractive Index of Ambient Medium
r1 -Radius of Curvature of the First Surface
r2 - Radius of Curvature of the Second Surface

Basically, the Lensmaker Equation is used to make Lenses. This online calculator helps you dynamically to determine the focal length of the lens.
