# Geometric Construction of Images in Spherical Mirrors

An object point placed in front of a spherical Gaussian mirror, whether concave or convex, will have its image formed from the intersection between two or more reflected rays by virtue of two or more incident rays.

Remembering that the reflected rays are conditioned to the properties of spherical Gaussian mirrors.

Be a convex Gauss mirror, the object situated on the main axis of the mirror in any position, will have its image on the main, virtual, right and minor axis with respect to the object.

Be a concave Gaussian mirror, the object situated on the main axis of the mirror before the center of curvature will have its image on the main axis, real, inverted and minor with respect to the object.

Whether it is a concave Gaussian mirror, the object situated on the principal axis of the mirror at the center of curvature will have its image on the principal axis, real, inverted and of the same size with respect to the object.

Let it be a concave Gaussian mirror, the object situated on the principal axis of the mirror at the focus will have its improper image formed (formed at infinity).

Be a concave Gaussian mirror, the object situated on the principal axis of the mirror between the focus and the vertex will have its image on the principal, virtual, right and major axis with respect to the object.

On the main axis, in all the situations mentioned, three points are taken as a reference: v – vertex, f – focus and c – center of curvature.
