Tsunamis are fast-moving waves often generated by underwater earthquakes. in the deep ocean their amplitude is barely noticable, but upon reaching shore, they can rise up to the astonishing height of a six-story building.
one tsunami, generated off the aleutian islands in alaska, had a wavelength of 732 km and traveled a distance of 3650 km in 4.59 hours.
(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
