Why “photoacoustics” is a great word
Photoacoustics is the science of acoustic waves generated when a material absorbs modulated light, a sonification of the photon. From the combining form photo- (from Greek phōs, phōt- 'light') and acoustics (from Greek akoustikos 'of or for hearing'), thus 'the acoustics of light'. Unlike acoustics (the general study of sound in air and matter) or optics (the domain of refraction and reflection), photoacoustics describes the precise moment when illumination becomes audition. It is the subtle thermal ping of a laser pulse striking a blood vessel, the microscopic pressure wave rising from stained tissue, or the hidden resonance within a gas cloud that only light can make speak—a revelation that the universe communicates through translation.
Etymology
