Tsunamis are fast-moving waves often generated by underwater earthquakes. In the deep ocean their amplitude is barely notical but upon reaching shore, they can rise up to the astonishing height of a six-story building. One tsunami, generated off the Aleutia islands in Alaska, had a wavelength of 679 km and traveled a distance of 3410 km in 4.93 h. (a) What was the speed (in m/s) of the wave? For reference, the speed of a 747 jetliner is about 250 m/s. Find the wave's (b) frequency and (c) period.
