Main Body

P waves can travel only through solid state.

Upon analysis it was found that:

1Till 101° - both S and P waves were received.
2Between 103° and 108° - shadow zone for both the waves.
3Beyond 108° only S-waves were received.

Inference on interior structure:

1Most of the earth's internal structure is [illegible] - Crust
2Core (part of the earth is made up of solid layers
3Deflection in the S-waves tell about the density difference between crust - mantle - core
4It also helps in analysing o density of different materials eg) Nife layer

This model has successfully provided an insight into earth's interior and help to predict earthquakes impact.

This is a continuation from previous page
  • Completes the analysis of seismic wave behavior
  • Provides specific angle measurements (101°, 103°, 108°) showing precise knowledge
  • Explains how wave patterns reveal structural information
  • Connects wave refraction to density differences
  • Concludes with practical application (earthquake prediction)
