A tsunami,an ocean wave generated by an earthquake,propagates along the open ocean at 700 km/hr and has a wavelength of 750 km.What is the frequency of the waves in such a tsunami?
A)0.93 Hz
B)0.00026 Hz
C)1.1 Hz
D)6.8 Hz
E)0.15 Hz

Question

Quizplus · Accepted Answer

Frequency (f) is given by the formula f = v/λ, where v is the speed of the wave and λ is the wavelength.

In this case, v = 700 km/hr = 194.4 m/s (converted to meters per second) and λ = 750 km = 750,000 m.

Plugging in these values, we get f = 194.4/750,000 = 0.0002592 Hz, which can be rounded to 0.00026 Hz. Therefore, the correct answer is B.
