The terms Primary wave and Secondary wave are used in seismology (the study of things like earthquakes). These are two different sorts of waves which can travel through the earth and be detected some distance away. The P wave travels faster and gets there sooner so it is called "Primary" (First). The other follows and gets there later so is called "Secondary" (Second). The primary wave is called a compression wave like a sound wave travelling through air. Each particle in the medium (substance wave travels through) pushes on the next one and builds up pressure which pushes back. In other words, the particles move back and forth along the same direction as the wave travels. The S wave is also called a shear wave. This is where the particles move sideways to the direction of motion of the wave. P waves have a typical speed through the earth at between 6 and 10km/sec (4 and 6 miles/sec). S waves travel between 3 and 7km/sec (2 to 4 miles per second). It is the study of these waves after earthquakes that allowed us to discover what the interior of the earth is made of.
What else can I help you with?
Which is faster a primary wave or a secondary wave?
Primary waves (P-waves) travel faster than secondary waves (S-waves) through the Earth's interior. P-waves are compressional waves that can travel through solids, liquids, and gases, while S-waves are shear waves that only travel through solids.
From which of the following do primary and secondary waves move outward?
Primary waves (P-waves) move outward from the focus of an earthquake, while secondary waves (S-waves) also move outward from the focus. Both types of waves are seismic body waves that travel through the Earth's interior.
What are the three diffrent kinds of seismic waves?
The three main types of seismic waves are P-waves (primary waves), S-waves (secondary waves), and surface waves. P-waves are compressional waves that travel the fastest and can move through both solids and liquids. S-waves are shear waves that move more slowly and only travel through solids. Surface waves are the slowest and travel along the surface of the Earth, causing the most damage during an earthquake.
Waves produced by earthquakes are called?
Waves produced by earthquakes are called seismic waves. These waves can be further categorized into primary (P-waves), secondary (S-waves), and surface waves.
The waves that arrive after primary waves they move the ground back and forth?
These waves are called secondary waves, or S-waves. They travel at slower speeds than primary waves and move the ground side-to-side, causing shaking and structural damage to buildings. S-waves are more destructive than P-waves and are usually felt after the initial P-wave motion during an earthquake.
Are the primary waves faster then the secondary waves?
Primary seismic waves travel the fastest.
What are the waves that arrive after primary waves in the Earth?
Secondary waves.
What waves are there for earthquakes?
Primary waves, Secondary waves, and Seismic waves
What type of waves are genered by earthquakes?
Primary Waves, Secondary Waves, and Surface Waves.
What types of waves are in an earthquake?
P waves (primary waves) and S waves (secondary waves).
What wave do earthquakes make?
Seismic waves Types: Primary waves Secondary waves Surface waves
Why are earthquake waves called primary secondary and surface?
Primary and secondary refer to the order in which they come out, surface waves are called surface because they resonate close to the surface
What are the two descriptive words for P in P Waves and the S in Swaves?
For P waves, the two descriptive words are Primary (or compressional) waves, while for S waves, the two words are Secondary (or shear) waves.
What are the different types of earthquakes waves?
The three types of earthquake waves are primary waves, surface waves, and secondary waves.
What does secondary waves and primary waves tell geologist?
how far away you are from the focus of an earthquake
Waves from an earthquake are know as these?
P or primary wave, S or secondary waves, L as in something waves
Waves from earthquakes are know as these?
P or primary wave, S or secondary waves, L as in something waves
