Spherical Mirrors Vs. Parabolic Mirrors
Reflexion on a Spherical Surface
Spherical Mirrors: Concave mirror, Linear object
★Parabola 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.
