Fano mechanism is the universal explanation of asymmetric resonance appearing in different systems. We report the evidence of Fano-like resonance in selective reflection from a resonant two-level medium. We draw an analogy with the asymmetric resonance previously obtained for the coupled oscillators. We also take into account the effects of dielectric background and local-field correction and connect our results with optical bistability.
