A tsunami (tidal wave) traveling across deep water can have a speed of 750 km/h and a wavelength of 350 km . what is the frequency?

...
general formula
v = f L
750 = f * 350
f = 2.14 h^-1
2.14 h^-1 * 1 h/3600s = 5.95E-4 Hz

You may have to wait an hour to award BA.

At L/V = T the period; so V/L = 1/T = F the frequency. And that's 750 km/hr//350 km = 2.14 cycles/hr. ANS.

Here's a question for you. Given the answer above, when the water on the beach you're swimming at suddenly recedes leaving the coast line and you high and dry, how long before that tsunami wave crashes in on you?

HINT: The recession is the trough, the crest comes 1/2 wavelength later.
