## Question:

What is the wavelength (m) of an earthquake that shakes you with a frequency of 11.5 Hz and gets to another city 85.0 km away in 12.0 s?

## Wave

A wave is a disturbance traveling from one place to another but the particles of the medium just vibrate at the mean position. The basic wave equation relates the wave speed {eq}v {/eq}, wavelength {eq}\lambda {/eq} and frequency {eq}f {/eq} of the wave.

{eq}\begin{align} v = \lambda f \end{align} {/eq}
