Answer:
Explanation:
P WAVES are also called Primary waves. The properties of a primary wave include:
• They are longitudinal and compressional waves by nature
• They travel much faster than other waves
• They travel through the earth to reach the seismograph stations first
• They can travel through any kind of material, including fluids
• They travel at the speed of sound, so they travel at the speed of sound
S WAVES are also called Secondary waves. The properties of a secondary wave include:
• They are transverse and shear waves in nature
• They arrive at the seismograph stations after the fast- movign P-waves
• They can travel onlt through solids
• They are slower than P-waves,a nd speeds are normally 65% of that of P-waves
