Use the spherical mirror equation to solve for focal length, object distance, or image distance.
Last updated: June 2026 | By Patchworkr Team
The mirror equation links three quantities for spherical mirrors. If the denominator becomes zero, the corresponding value is not finite.
Concave mirrors are commonly treated with positive focal length, while convex mirrors are negative. Real and virtual images follow the same convention used in optics texts.
