Q. Consider the following seismic waves: - Primary waves
- Secondary waves
- Rayleigh waves
- Love waves
Which of the above are classified as surface waves?
Answer:
Only 3 and 4
Notes: Rayleigh waves and Love waves (statements 3 and 4) are surface waves that travel along the Earth's surface and are responsible for most ground shaking during earthquakes. In contrast, Primary (P) and Secondary (S) waves (statements 1 and 2) are body waves that travel within the Earth's interior rather than along its surface.
