explain primary waves in details
Answers
The Primary wave is also known as the pressure wave or primary wave. It is a kind of elastic body wave known as seismic waves. The P wave moves faster as compared to seismic waves. They are the first signal that we get when an earthquake arrives at the affected location. They can transmit via solids, liquids, and gases.
Introduction to the P wave
We refer to it as a primary wave and is of high velocity. It forms from alternating rarefactions and compressions. Further, it is the primary wave that records in the seismograph. Other ways are S waves or secondary waves that reach after P waves. The S waves are slower and the average speed is 65 percent of P waves. In this article, we are discussing in detail P waves.The P waves travel on the Earth. The behavior of P waves is analyzed to probe the Earth’s structure. The difference in velocity indicates the changes in composition or phase.
