How do you determine the difference in time between the arrival of the primary (p) wave and the arrival of the secondary (s) wave during an earthquake? (in other words, how do you determine t? )add the s and p wavessubtract the s from the p wavesubtract the p from the s wavemultiply the s and the p waves

Correct Subtract the p from the s

The study of earthquake is known as seismology, it study its effect and waves form. The two seismic waves studied in earthquake are P wave and S wave. P-wave is known as primary wave and S-wave is known as secondary wave.

P-wave are fastest wave and it travels through solid, liquid and gas. S-wave are slower as compared to p-wave and are second to arrive, it could pass only through solid and could not pass through liquid and gas. They travel in perpendicular direction to the vibration of the particles.

Example: Suppose the P-wave arrives at t = 1.0 s and the S-wave arrives at t  = 6.0 s, then the difference between the arrival time of the P-wave and the S-wave can be calculated as:

Time Difference = 6.0 −1.0=5.0 s
