- Center of curvature (C): Center of the sphere from which mirror is cut
- Radius of curvature (R): Radius of the sphere from which mirror is cut

- Object beyond 2F: Image between F and 2F, real, inverted, diminished
- Object at 2F: Image at 2F, real, inverted, same size
- Object between F and 2F: Image beyond 2F, real, inverted, magnified
