The focal length of an equiconvex lens is equal to radius of curvature of either surface. What is the refractive index of the material of the prism ?

The focal length of an eqniconvex lens is equal to the radius of curvature of either face. What is the value of refractive index of the material same of the lens?

The focal length of a double convex lens is equal to radius of curvature of either surface. The refractive index of its material is

Statement-1 : Focal length of an equiconvex lens of mu = 3//2 is equal to radius of curvature of each surface. Statement-2 : it follows from (1)/(f) = (mu - 1)((1)/(R_(1)) - (1)/(R_(2)))

The focal length of an equi-convex lens is greater than the radius of curvature of any of the surfaces. Then, the refractive index of the material of the lens is

The focal lengtli of a equiconvex lens is 2/3 times the radius of curvature of the surface. What is the refractive index of the medium?
