Q. Consider the following statements:
- P waves or transverse waves
- L waves or longitudinal waves
- S waves or surface waves
Which of the above is / are correct?
Answer:
None of the above
Notes: There are three types of earthquake waves:
- P waves or longitudinal waves : P waves are also known as compressional waves because of the pushing and pulling they do. Subject to P waves, particles move in the same direction.
- S waves or transverse waves : S waves or shear wave is a seiomic body wave that shakes the ground back and forth perpendicular to the direction the wave is moving.
- L waves or surface waves. L waves is an earthquake wave that travels around the earth surface and is usually the third conspicious wave to reach a seismograph.
