Problem

A surface water wave travels in deep water at a speed of

1.5\,\text{m/s}

with a wavelength of

0.75\,\text{m}

. The wave then enters a shallow region where its speed is

1.2\,\text{m/s}

. What is the wavelength of the wave in the shallow region? a)

0.75\,\text{m}

0.90\,\text{m}

0.60\,\text{m}

0.48\,\text{m}
