Assignment:
Question 1. Tsunamis are fast-moving waves generated by underwater earthquakes. In the deep ocean their amplitude is barely noticeable, but upon reaching the 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 wave length of 650 km and traveled a distance of 3700 km in 5.6 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.
(b) Find the wave's frequency.
(c) Find the wave's period.
