1. Focal length: The focal length of a lens or mirror is the distance between the focal point and the optical center of the lens or mirror. It is a measure of how strongly the lens or mirror converges or diverges light.
2. Center of curvature: The center of curvature is the point located at a distance equal to the radius of curvature from the vertex of a curved mirror or lens. It is the center of the sphere of which the mirror or lens is a part.
3. Radius of curvature: The radius of curvature is the distance between the center of curvature and the vertex of a curved mirror or lens. It is half of the diameter of the sphere of which the mirror or lens is a part.
4. Principal axis: The principal axis is an imaginary line that passes through the center of curvature and the vertex of a curved mirror or lens. It is used as a reference line for measuring distances and angles in optical systems.
