Attempt this previous-year question. The correct option stays hidden until you choose.
Consider the following statements:
1. In a seismograph, P waves are recorded earlier than S waves.
2. In P waves, the individual particles vibrate to and fro in the direction of wave propagation whereas in S waves, the particles vibrate up and down at right angles to the direction of wave propagation.
Which of the statements given above is/are correct?
Pick an option to check yourself.
• Correct Answer: C
• P waves are the fastest seismic waves and arrive first at seismographs; S waves follow later.
• P waves are longitudinal with particle motion parallel to propagation; S waves are transverse with perpendicular motion.
• Both statements correctly describe seismic wave behaviour.
