Explanation:
Detailed explanation-1: -P-wave, S-wave, L-wave is the proper order of seismic waves as they are received at seismograph station. The first kind of body wave is the P wave or primary wave.
Detailed explanation-2: -P waves travel the fastest, so they arrive first. S waves, which travel at about half the speed of P waves, arrive later. A seismic station close to the earthquake records P waves and S waves in quick succession.
