A seismic wave has a velocity of 5000 m/s and a frequency of 4Hz. wht is the wavelength of this wave? if this was a light wave traveling in a vacuum with the same wavelength, what would be its period?

bobpursley,
frequency*wavelength=speedofPropagation
memorize that equation. It is called the wave equation.
Period = 1/frequency
