What is the wavelength of an earthquake wave if it has a speed of 14 km/s and a frequency of 4 Hz?

Answer: Wavelength = 3.5 km

Explanation:

The wave equation is given as:

v = f * λ - - - (1)

Where v = speed of the earthquake wave = 14 km/s = 14 * 1000 m/s

f = frequency of the earthquake wave = 4 Hz

λ = wavelength of the earthquake wave = ?

Plug in the values in Equation (1):

(1) = > 14 * 1000 = 4 * λ

λ = 3500 m

λ = 3.5 km
