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)0.00026 Hz
B)1.1 Hz
C)1100 Hz
D)930 Hz
E)0.93 Hz

Question

Quizplus · Accepted Answer

The frequency of a wave is calculated using the formula: frequency = speed / wavelength. Here, frequency = 700 km/hr / 750 km = 0.9333... km/hr, which converts to approximately 0.00026 Hz when converted to Hz (since 1 km/hr = 1/3600 Hz).
