Solution
The correct option is B 2 only
Explanation:
Statement 1 is correct: P waves, or Primary waves, are the first waves to arrive at a seismograph. P waves are longitudinal waves because the displacement of the medium is in the same direction or the opposite direction of the direction of propagation of the wave. They can travel in all mediums(gaseous, liquid and solid materials)
Statement 2 is incorrect: S waves, or secondary waves, are the second waves to arrive during an earthquake. They are much slower than P waves and can travel only through solids.
