A tsunami (tidal wave) traveling across deep water can have a speed of 750 km/h and a wavelength of 310 km. What is the frequency of such a wave?

A wave travels along a stretched horizontal rope. The vertical distance from crest to trough of this wave is 13 cm and the horizontal distance from crest to trough is 28 cm. What are (a) the wavelength and (b) the amplitude of this wave?

A surfer floating beyond the breakers notes 14 waves per minute passing her position. If the wavelength of these waves is 34 m, what is their speed?

A tsunami of wavelength 250 km and velocity 750 km/h travels across the Pacific Ocean. As it approaches Hawaii, people observe an unusual decrease of sea level in the harbors. Approximately how much time do they have to run to safety? (In the absence of knowledge and warning. people have died during tsunamis, some of them attracted to the shore to see stranded fishes and boats.)

A wave oscillates 5.0 times a second and has a speed of 6.0 m/s. What are the (a) frequency, (b) period, and (c) wavelength of this wave?

The speed of a tsunami (popularly known as a tidal wave, although it has nothing whatever to do with tides) depends on the depth of the water through which it is traveling. At a depth of d feet, the speed of a tsunami will be $s(d)=3.86 \sqrt{d}$ miles per hour. Find the speed of a tsunami in the Pacific basin where the average depth is 15,000 feet.
