Common questions

What is the Mirror Magnification formula?

Mirror Magnification is written M = -dᵢ/dₒ = hᵢ/hₒ. The ratio of image size to object size. Negative magnification indicates an inverted image. It belongs to Optics, under Reflection.

What are the units in M = -dᵢ/dₒ = hᵢ/hₒ?

In SI units, M is magnification (dimensionless); d_i is image distance, measured in m; d_o is object distance, measured in m; h_i is image height, measured in m; h_o is object height, measured in m.
