No, the aperture of a spherical mirror is not necessarily equal to its diameter. The aperture refers to the effective opening through which light can enter and be reflected by the mirror, which can be smaller than the overall diameter of the mirror. In many cases, the aperture is defined by the area of the mirror that is used for focusing light, while the diameter is simply the total width across the mirror.

Meaning of aperture in spherical mirror?
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.
What is the center of spherical mirror?
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
What part of a reflecting telescope would you measure to find the apeture?
To find the aperture of a reflecting telescope, you would measure the diameter of the primary mirror. The aperture of a telescope is the diameter of its primary light-gathering element, which in the case of a reflecting telescope, is the primary mirror.
How is the size of a reflecting telescope indicated?
The size of a reflecting telescope is typically indicated by its aperture, which is the diameter of the primary mirror. Aperture size plays a crucial role in determining the light-gathering ability and resolving power of the telescope.
Does a broken piece of a spherical mirror works as another spherical mirror?
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.
Is plane mirror a spherical mirror why?
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

When was Still Life with Spherical Mirror created?
Still Life with Spherical Mirror was created in 1934.
What are uses of spherical mirror?
that mirror is mystery
What is the center of spherical mirror is called?
The center of a spherical mirror is called the vertex. This is the point where the principal axis intersects the mirror's surface.
Is a hubcap a converging spherical mirror?
No, a hubcap is not a converging spherical mirror. A hubcap is a protective covering for the center of a vehicle's wheel, while a converging spherical mirror is a mirror that curves inwards to focus light rays at a point.
What is the Lens aperture of the hubble telescope?
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).
