Consider the following statements:

1. P - waves are analogous to light waves.
2. S - waves are analogous to sound waves.
3. P - waves travel faster in solid and slower in liquid medium.
4. L - waves start after the interface of P and S waves on the surface.

Which of the above given statements is/are incorrect?

P-waves are the first to arrive, i.e. they travel fastest. These are 'push-pull' waves analogous to sound waves, in which each particle moves back and forth. S wave is the secondary wave. It is a transverse wave, which means the particles of its medium move at right angles to the energy that is being transferred. S waves are analogous to ocean waves, as the water molecules oscillate only up or down while the wave itself can move many miles from the origin.
