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 Aletian islands in Alaska, had a wavelength of 623 km and traveled a distance of 3160 km in 5.23 h.

1km=1000m & 1hour=3600s so:
v(speed)=((3160x1000)/(5.23x3600)m/s
L:wave lenght
frequency=speed/wavelength=v/L
Period=1/f(frequency)

NO. the cost measures the time that makes the wave to return and forth on a given distance. The frequency little extra frustrating. you recognize that the amplitude of a wave varies In some place , you have a optimum , some others a minimum some others 0. the area between 2 optimum is named the wavelength The frequency is comparable to the cost divided via the wavelength

I'm sure you can convert km to meters and hours to seconds, so you can figure the speed for yourself. Frequency*wavelength= speed and period is the reciprocal of frequency.
