Solving a problem in physics section 37 point 11 optic

11. The spherical surface of a plano-convex lens (n1 = 1,52) in contact with the glass plate (n2 = 1,7). The space between the lens, the radius of curvature R = 1 m, and the plate is filled with fluid. Watching Newton´s rings in reflected light (λ0 = 0,589 m), measured the radius rk tenth dark ring. To determine the refractive index of the liquid nzh in two cases: 1) rk = 2,05 mm 2) rk = 1,9 mm.
