Atomic coherences and squeezing of the resonance fluorescence are investigated for three-level atoms of the \ensuremath{\Lambda} configuration. An experimental scheme is proposed for direct observation of the atomic coherence in the lower states, based on switching the phase difference of the pump lasers. Squeezing of the resonance fluoresence of three-level atoms is predicted even when long-lived atomic coherences exist.
