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
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.
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.
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.
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.
primary
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.
This is known as the focus or hypocentre of an earthquake.
epicenter
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.
The point on the Earth's surface directly above the earthquake's origin is called the "epicenter." It is the location where seismic waves radiate outwards from the earthquake's focus (or hypocenter) beneath the surface.
