An underwater sonar transducer emits a longitudinal acoustic wave that travels through seawater. The wavelength of the sound wave is 3.75 cm.
(Speed of sound in seawater = 1.50 × 103 m s-1)
Calculate the frequency f f\,f of the transmitted sound wave.
The acoustic wave is generated by the front face of the transducer oscillating with simple harmonic motion. Calculate the maximum acceleration amaxa_{\text{max}}amax of this face when it oscillates with an amplitude of 1.5 × 10-5 m.
