Principal axis: The line connecting the curvature's centre (C) and the pole (P). The mirror at its pole is typical.
Aperture: The spherical mirror's diameter is referred to as its aperture. It symbolises the mirror's reflecting surface.The definition of pole, the center of curvature, the radius of curvature, principal axis, aperture, focus, and focal length of a spherical mirror is mentioned above.
Focus: The major axis point at which the parallel rays of light either actually meet (in a concave mirror) or appear to meet (in a convex mirror) after reflection. F is used to symbolise it.
Focal Length: The focal length of a spherical mirror is the distance between the main focus and pole. F is used to signify it.
Focal length f = PF
Summary:
Define the pole, the center of curvature, the radius of curvature, principal axis, aperture, focus, and focal length of a spherical mirror.
A spherical mirror's centre of curvature, major axis, aperture,radius of curvature, focus, and focal length are all described above. A spherical mirror is a mirror with a cut-out spherical surface. There are two types of spherical mirrors: concave and convex mirrors.
