[b][i]Reflexion on a Spherical SurfaceSpherical Mirrors: Convex mirror, Linear object
★Enable the disabled points to see the paraboloid with the same focus.
★Paraboloid plotted with equal focus f = (- 2.0) as the approximate spherical mirror.
★The parabole does not generate the error FOCUS.
★The spherical mirror fails for angles that deviate from its approximate coincidence with the parabola.[/i][/b]
