Explanation:
Detailed explanation-1: -S Waves. The second type of body wave is the S wave or secondary wave, and are easy to remember because they’re the second wave to arrive after an earthquake. An S wave is about 1.7 times slower than a P wave. The biggest difference is that S waves can’t move through liquids.
Detailed explanation-2: -Secondary waves cause the rocks they pass through to change in shape. These waves are the second fastest traveling seismic waves (after primary waves) and can travel through solids but not through liquids or gases. Also called shear wave S wave See Note at earthquake.
