Photothermal vibration was observed in water for a stainless-steel membrane with a cantilever structure. The resonance frequency obtained was low compared with that in air, and resonance sharpness Q was considerably smaller (Q=7) than that in air (Q=200). The frequency shift compared to the air resonance case was explained by sound radiation in water.
