Which of the following is NOT correct about Earth quake waves?

P waves move faster than S waves

P waves can travel through gaseous materials

S waves can travel through solids

Earth quakes can give information about earth's rock composition

Primary Waves (P waves)

P-waves are also known as the longitudinal or compressional waves.

They are Analogous to sound waves.

Particles of the medium of P-waves vibrate along the direction of propagation of the wave.

They move faster and are the first to arrive at the surface.

P-waves are of high frequency.

They can travel in all mediums.

Velocity Solids > Liquids > Gases.

Secondary Waves (S waves)

S-waves Also called as transverse or distortional waves.

They are analogous to water ripples or light waves.

Arrives at the surface with some time lag.

A secondary wave cannot pass through liquids or gases.

These waves are of high frequency waves.

Travel at varying velocities (proportional to shear strength) through the solid part of the Earth’s crust, mantle.

but earthquakes do give us info about earth's rock composition
