- Homework Statement
- Determine the optical power of a biconvex lens, with a radius of curvature of both spherical surfaces of 20 cm each, which is made of glass with a refractive index of 1.83 in water. The refractive index for water is 1.33
- Relevant Equations
- Optical power=1/focal length of lens
Hello. I need formulas for the focal length of a lens when I have refractive indices of two centers and two radii of curvature of spherical surfaces or one radius of curvature of spherical surfaces. I search the internet but can't find it.
