[b][i]Reflexion on a Spherical SurfaceSpherical Mirrors: Convex mirror, Linear object[/i][/b] ★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.
