<p>A measuring apparatus includes an acoustic wave detecting unit that detects acoustic waves generated from a subject irradiated with light, and a member that is disposed between the acoustic wave detecting unit and the subject and that has an acoustic speed value smaller than an average acoustic speed value inside the subject. The thickness of the member is greater than a value obtained by dividing the acoustic speed value inside the subject by the minimum frequency detectable by the acoustic wave detecting unit.</p> |
