Question

2 poin6. What is the speed of an earthquake wave if it has a wavelength of2300 m and a frequency of 3 Hz? *6900 m/s5300 m/s6000 m/s1300 m/s

Answer 1

Given that the wavelength of the wave is

`\lambda=2300\text{ m}`

The frequency of the wave is f = 3 Hz

We have to find the speed of the wave.

Let the speed of the wave is v.

The speed can be calculated by the formula,

`v=f\lambda`

Substituting the values, the speed of the wave will be

`\begin{gathered} v=\text{ 3}*2300 \\ =6900\text{ m/s} \end{gathered}`

Thus, the speed of the wave is 6900 m/s.
