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 Aleutian islands in

Alaska, had a wavelength of $607km$ and

traveled a distance of $3470km$ in $5\mathrm{.}83h.($a$)$

What was the speed $($in $\frac{m}{s})$ of the wave? For

reference, the speed of a $747$ jetliner is about

$250\frac{m}{s}.$ Find the wave's $($b$)$ frequency and $($c$)$

period.
