Which wave type travels fastest in seismic methods?
A. Surface wave
B. Secondary wave (S-wave)
C. Love wave
D. Primary wave (P-wave)
Answer: Option D
Solution (By Examveda Team)
Primary (P) waves are the fastest seismic waves and are the first to arrive at a detector.They are compressional in nature.This Question Belongs to Geological Engineering >> Geophysical Methods In Engineering
