How does a mechanical wave move?
A mechanical wave is a wave that is an oscillation of matter, and therefore transfers energy through a medium. Therefore, the oscillating material does not move far from its initial equilibrium position. Mechanical waves transport energy. This energy propagates in the same direction as the wave.
Which wave has more energy?
gamma-rays
What color has the most energy?
violet
Which waves travel the fastest?
Surface waves travel along the surface. There are two types of body waves: P-waves travel fastest and through solids, liquids, and gases; S-waves only travel through solids. Surface waves are the slowest, but they do the most damage in an earthquake.
Which is faster S or P-waves?
P-waves and S-waves are body waves that propagate through the planet. P-waves travel 60% faster than S-waves on average because the interior of the Earth does not react the same way to both of them. The energy is thus less easily transmitted through the medium, and S-waves are slower.
Where do P-waves travel the fastest?
mantle
What causes an S wave?
This is known as an S wave and represents depolarisation in the Purkinje fibres. The S wave travels in the opposite direction to the large R wave because, as can be seen on the earlier picture, the Purkinje fibres spread throughout the ventricles from top to bottom and then back up through the walls of the ventricles.
Where does S waves travel?
S waves move rock particles up and down, or side-to-side–perpendicular to the direction that the wave is traveling in (the direction of wave propagation).
What is the difference between S waves and P waves?
P waves travel at speeds between 1 and 14 km per second, while S waves travel significantly slower, between 1 and 8 km per second. The S waves are the second wave to reach a seismic station measuring a disturbance. The difference in arrival times helps geologists determine the location of the earthquake.
What is the difference between P waves S waves and surface waves?
P waves can travel through solids, liquids, and even gases. Unlike P waves, S waves can travel only through solid materials. After both P and S waves have moved through the body of Earth, they are followed by surface waves, which travel along Earth’s surface. Surface waves travel only through solid media.
What are two characteristics of P-waves?
Although liquids and gases have zero rigidity, they have compressibility, which enables them to transmit P-waves. Sound waves are P-waves moving through the air….P-Waves.
| P-waves travel through materials with rigidity and/or compressiblity, and density | |
|---|---|
| greater compressibility | faster P-waves |
| greater density | slower P-waves |
