Trace principal rays off a curved mirror to find the image. Concave mirrors focus and can flip the image; convex mirrors always give a small upright virtual image.

Equation1/v + 1/u = 1/f

Governing equation

\frac{1}{f} = \frac{1}{d _{o}} + \frac{1}{d _{i}}, M = - \frac{d _{i}}{d _{o}} = - 1.20 (f = 120, d_{o} = 220)

Reading this result: Object between F and C: the image is real, inverted, and magnified (-1.20×), projected in front of the mirror.
