(7a) Tsunamis are fast-moving waves often generated by underwater earth quakes. In the deep ocean their amplitude is barely noticeable, but upon reaching shore, they can rise up to the astonishing height of a six story building. One tsunami, generated near the Aleutian islands in Alaska, had a wavelength of 870 km and traveled a distance of 4030 km in 5.5 h. What was the speed (in m/s) of the wave? Tries 0/10 (7b) What is the frequency of the wave? :] Tries 0/10 (7c) What is the period of the wave? : Tries 0/10
