1. on december 26, 2004, a great earthquake occurred off the coast of sumatra and triggered immense waves (tsunami) that killed some 200,000 people. satellites observing these waves from space measured 800 km from one wave crest to the next and a period between waves of 1 hour. what was the speed of these waves in m/s and in km/h? does your answer help you understand why the waves caused such devastation?

222.22 m/s is how fast these waves are moving. Relationship between wave speed, wavelength, frequency, and period.

How can I determine the wave speed?

The equation wave speed = frequency x wavelength describes the relationship between wave speed, wavelength, frequency, and period.

Reason: A. Given that we are aware that the formula for calculating a wave's speed is:

v = f, where v is the wave's speed.

f = the wave's frequency

A wavelength is

Here, stands for the separation between adjacent wave crests.

f = 1/Time Period = (1/1 hr)(1 hr/3600 s) f = 2.77 x 104 s1 = 800 km = 8 x 105 m

Therefore,

v = (2.77 x 10⁻⁴ s⁻¹)(8 x 10⁵ m)

v = 222.22 m/s.
