The geometric centre of a spherical mirror is called its pole. The centre of the hollow sphere for which the mirror is a part, is called the centre of curvature. The line joining the centre of curvature and the pole is the principal axis. A light ray incident on a spherical mirror, after reflection appears to pass through the principal focus in the case of a convex mirror and passes through the focus in the case of concave mirror. The diameter of the spherical mirror gives the measure of its aperture
Mirror reflect the light that enters into it. The plane surface area of the mirror through which the light rays enter is called aperture. If we place some opaque object with hole in its center , in-front of the mirror now light can enter only through this hole. Now the aperture of the mirror is reduced.
Yes, spherical mirror is the part of a spherical reflecting surface.when it is broken the broken piece is also the part of the spherical reflecting surface.
real and virtual images are formed by spherical mirror .
plane mirror is never a spherical mirror,spherical mirrors are made up by cutting the part of the sherical balls and then polishing them.while the plane mirror is just a sheet of polished glass

that mirror is mystery
Still Life with Spherical Mirror was created in 1934.
no
The Hubble Space Telescope is a reflector, so its objective is not a big-moose lens at the front;it's a big mirror in the back.The diameter of the objective mirror is 2.4 meters(7.87 feet), (94.5 inches).
Yes
The center of the spherical reflecting surface of the mirror is called the pole of the mirror.
