That's wrong the correct answer is Reflection

Answer:

When a seismic wave 'bounces backward' and reaches a boundary, it is called Reflection.

Explanation:

  • The seismic waves are the result of the landslides, earthquakes, volcanic eruptions, explosions by humans.
  • They are the energy waves which travel through the earth's layers. To study the interior of the Earth, reflection of seismic waves is studied.
  • When a wave reaches a 'boundary', there can be infinite paths it can take while bouncing back.
  • This process is called reflection. Each path is noted with a 'set of letters' describing the phase and the trajectory.
  • The 'upper case' represents the transmitted waves and the 'lower case' represents the reflected wave.
