What is the difference between parabolic and concave mirrors?
In the case of concave mirrors parallel rays, parallel to the principal axis and incident near the pole(axial rays), after reflection will converge to the principal focus.Rays reflected from the marginal portions of the mirror(marginal rays) will converge to points nearer than the focus. Due to this the image formed by a concave mirror of large aperture will be blurred. This defect is called spherical aberration. This defect can be overcome by using parabolic mirrors. In a parabolic mirror all the rays, axial rays as well as the marginal rays, incidenting on it after reflection will converge to the same principal focus. This is due to the geometric property of the parabola, that is parabola allows only one focus.Hence in a parabolic mirror there is no spherical aberration and the image will be sharp and clear.
