The seismic weaves helps in understanding the interior of earth. Which of the following about seismic waves is/are correct ?
1. P waves travel with fastest speed and are most destructive.
2. S waves cannot pass through liquid.
3. The surface waves (L) are analogous to light waves.
Select the correct answer using the codes given below.
1 and 2 only
2 only
2 and 3 only
1 and 3 only
Explanation:
Though P waves travel with fastest speed, they are not most destructive. L waves are most violent and destructive. It’s the S waves that are analogous to light waves because S waves are transverse in the nature and the particle moves at right angles to the direction of propagation.
