A plano-convex lens of unknown material and unknown focal length is given. With the help of a spherometer we can measure the :
(1) refractive index of the material
(2) focal length of the lens
(3) radius of curvature of the curved surface
(4) aperture of the lens
(1) refractive index of the material
