Consider the statements regarding earthquake (seismology).
1) Primary waves are analogous to sound waves and it can travel through liquid medium.
2) Secondary waves are analogous to water ripples and it cannot pass through liquid medium.
3) Surface waves are most destructive and slowest among the three waves (primary, secondary, surface waves).
Choose the incorrect statement/s from the following codes.

1, 2 only.
3 only.
2, 3 only.
None of the above.
Explanation:
Primary waves (P-waves) are compressional waves that are longitudinal in nature. Thesewaves can travel through any type of material, including fluids, and can travel at nearlytwice the speed of Secondary waves.Secondary waves (S-waves) are shear waves that are transverse in nature. S-waves cantravel only through solids, as fluids (liquids and gases) do not support shear stresses.
