16. 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?
(a)
1 only
(b)
2 only
(c)
Both 1 and 2
(d)
Neither 1 nor 2
Explanation
Ans: (c)
Yes, in a seismograph, P waves are recorded earlier than S waves.
Yes, P waves
vibrate parallel to the direction of the waves. Thus, this leads to particles vibrating
to and fro in the direction. And S waves
travel like ocean waves, which are perpendicular to the direction. Thus, this
leads to particles vibrating up and down at the right angles to the direction.
