Tsunamis are fast-moving waves often generated by underwater earthquakes. In the deep ocean their amplitude is barely noticeable, but upon reaching shore they can rise to an astonishing height of a six-story building. One tsunami generated off the Aleutian Islands in Alaska, had a wavelength of 897km and traveled a distance of 3280km in 4.18h. (a) What was the speed (in m/s) of the wave? Find the waves (b) Frequency and (c) Period.
