P waves
Q. Where are seismic waves the most powerful?
Seismic waves can be classified into two basic types: body waves which travel through the Earth and surface waves, which travel along the Earth’s surface. Those waves that are the most destructive are the surface waves which generally have the strongest vibration.
Q. What are the 3 types of seismic waves?
There are three major kinds of seismic waves: P, S, and surface waves. P and S waves together are sometimes called body waves because they can travel through the body of the earth, and are not trapped near the surface.
Q. What does a seismic wave move?
Body waves can travel through the earth’s inner layers, but surface waves can only move along the surface of the planet like ripples on water. Earthquakes radiate seismic energy as both body and surface waves. The P wave can move through solid rock and fluids, like water or the liquid layers of the earth.
Q. How do P waves and S waves move?
P waves can travel through solids, liquids, and even gases. S waves shake the ground in a shearing, or crosswise, motion that is perpendicular to the direction of travel. These are the shake waves that move the ground up and down or from side to side.
Q. Which set of waves are the S waves?
transverse waves
Q. What does S wave mean?
shear wave
Q. What type of wave is P wave?
Primary waves
Q. Why are S waves slower?
S-Waves. Secondary , or S waves, travel slower than P waves and are also called “shear” waves because they don’t change the volume of the material through which they propagate, they shear it. As a transverse wave passes the ground perpendicular to the direction that the wave is propagating. S-waves are transverse waves …
Q. Which waves are fastest light sound water?
The speed of sound through air is about 340 meters per second. It’s faster through water and it’s even faster through steel. Light will travel through a vacuum at 300 million meters per second. So they’re totally different scales.
Q. Does light travel faster in water?
Explain that unlike sound, light waves travel fastest through a vacuum and air, and slower through other materials such as glass or water.
