Answer:
Wave A can travel through liquids but Wave B cannot travel through liquids.
Explanation:
We need to identify the waves first:
On a seismograph, the first wave to arrive a Seismic station are the P waves. The Primary or P waves are the ones at A.
The waves at B are the secondary waves that arrives later at the station. These secondary waves or S waves are shear waves.
P waves are faster than S waves and they are the first waves picked on a Seismic station.
P waves can pass through any material be it solid, liquid or gas.
S waves are shear waves and only pass through solid medium. As liquids are not capable of shearing, they get cut off in liquid interphase.
Both S and P waves are elastic in nature. They are both body waves.
