Problem

To examine a metal block immersed in water, an engineer wants ultrasound with a wavelength of

0.50\,\text{mm}

. If the speed of sound in water is

1480\,\text{m\,s}^{-1}

, the frequency that should be selected is closest to a)

1.48\,\text{MHz}

5.92\,\text{MHz}

2.96\,\text{MHz}

0.296\,\text{MHz}
