What is the wavelength of an earthquake wave if it has a speed of 15 km/s and a frequency of 12 Hz?

Natasha2012 [34]

<h2>Answer: 1.25 km</h2>

Explanation:

The velocity $V$ of a wave is given by:

$V=\lambda.f$ (1)

Where:

$\lambda$ is the wavelength of the wave

$f$ is the frequency of the wave. Its unit is Hertz ( $1Hz=\frac{1}{s}$ )

So, we have to find $\lambda$ from equation (1):

$\lambda=\frac{V}{f}$ (2)

$\lambda=\frac{15km/s}{12Hz}$

Finally we obtain the wavelength of the earthquake wave:

$\lambda=1.25 km$
