Primary and secondary refer to the order in which they come out, surface waves are called surface because they resonate close to the surface
Eg. in an earthquake, they are called the primary and the secondary sound waves. grrrrrr
The energy radiated in all directions from its source after an earthquake is called seismic waves. These waves include primary waves (P-waves), secondary waves (S-waves), and surface waves, which propagate through the Earth and carry the energy released during the earthquake. Seismic waves are responsible for the shaking and damage experienced during and after an earthquake.
No. the primary winding is called the primary; the secondary winding is called the secondary. These are both wrapped around the iron core of the transformer. The core helps magnetically link the primary and secondary, which causes the transformation of voltage and current from primary to secondary.
When an earthquake occurs, the energy radiates in all directions from its source, known as the focus or hypocenter. This energy travels in the form of seismic waves, which are classified into primary (P) waves and secondary (S) waves. The point directly above the focus on the Earth's surface is called the epicenter. These seismic waves are what we feel during an earthquake.
Seismic waves affect us because they are what causes the motion from an earthquake that destroy buildings and such. The three types of seismic waves are surface waves primary waves also called P-waves and secondary waves also called S-waves.
Some consumers are called "primary consumers" and others are called "secondary consumers" because the primary consumer is the first consumer and a secondary is the second consumer.
Vibrational tremors sent out from an earthquake are called seismic waves. There are three main types: P waves (primary waves) are the fastest and can travel through solids, liquids, and gases. S waves (secondary waves) are slower and only travel through solids. Surface waves are slower but cause the most damage as they travel along the Earth's surface.
During an earthquake, seismic waves are released. These waves travel through the Earth and can be detected by seismographs. The main types of seismic waves are P-waves (primary waves), S-waves (secondary waves), and surface waves.
The point on the earth's surface closest to the origin of an earthquake is called the epicenter. This is where the seismic waves generated by the earthquake first reach the surface.
This is known as the focus or hypocentre of an earthquake.
primary
Scientists use devices called Seismographs to determine the epicenter of an earthquake. If 3 or more seismographs detect an earthquake, seismic wave activity can be measured and quantified and then cross-referenced with other data (the primary and secondary seismic waves) to determine the earthquake's location.
