Final answer:

To find the frequency of the tsunami wave, use the formula frequency (f) = speed (v) / wavelength (λ). With the speed of 970 km/h and a wavelength of 450 km, the frequency is approximately 0.00059876 Hz.

Step-by-step explanation:

The student is asking about the calculation of the frequency of a wave given its speed and wavelength. The frequency of a wave can be found using the formula: frequency (f) = speed (v) / wavelength (λ). Given a tsunami traveling at a speed of 970 km/h (which we convert to 970,000 meters per hour and then to 269.44 meters per second to keep units consistent) and a wavelength of 450 km (which is 450,000 meters), we can calculate the frequency.

So, the calculation will be: frequency (f) = 269.44 m/s / 450,000 m, which equals 0.00059876 Hz. Therefore, the frequency of the tsunami is approximately 0.00059876 Hz.

Answer:

Frequency of wave = 2.16 Hz (Approx)

Step-by-step explanation:

Given:

Speed of tsunami = 970 km/h

Wavelength = 450 km

Find:

Frequency of wave

Computation:

Frequency = Speed / Wavelength

Frequency of wave = Speed of tsunami / Wavelength

Frequency of wave = 970 / 450

Frequency of wave = 2.16 Hz (Approx)
