Question
A seismograph located $1350 \mathrm{~km}$ from an earthquake detects seismic waves $4.64 \mathrm{~min}$ after the quake occurs. The seismograph oscillates in step with the waves, at $3.17 \mathrm{~Hz}$. Find the wavelength.
Step 1
First, we need to find the speed of the seismic waves. We know the distance and the time it took for the waves to reach the seismograph, so we can use the formula: speed = distance / time. Show more…
