Which seismic wave below arrives at the seismic recording station last?
a. Surface waves
b. P-waves
c. S-waves
d. Sound waves
e. Tidal waves
Answer:
The answer is a. surface waves. Explanation: Of the body waves (P and S-waves), P-waves are the fastest which travel through earth's interior at a velocity of 5-8 km/s, which is followed by S-waves which travel at a velocity of 3-5 km/s. Surface waves (Love and Rayleigh), as the name suggests, travel along the earth's surface and are the slowest of all. They travel at a velocity of 2.5-4.5 km/s.
