P waves are the&nbsp;<strong>fastest seismic waves and can move through solid, liquid, or gas.<\/strong>&nbsp;They leave behind a trail of compressions and rarefactions on the medium they move through. P waves are also called pressure waves for this reason.<\/li>\n\n\n\n<li><strong>P waves are longitudinal waves, which means that the particle motion occurs parallel to the direction of wave propagation<\/strong>. These waves are compression waves, where particles oscillate back and forth in the same direction that the wave is traveling. As a result,&nbsp;<strong>the individual particles vibrate to and in the direction of wave propagation.<\/strong><\/li>\n\n\n\n<li>On the other hand,&nbsp;<strong><a href=\"https:\/\/lotusarise.com\/seismic-waves-upsc\/\">S waves<\/a>&nbsp;are transverse waves, where particle motion occurs perpendicular (at right angles) to the direction of wave propagation<\/strong>. These waves cause the particles to move up and down or side to side perpendicular to the direction of the wave. Therefore,&nbsp;<strong>in S waves, the particles vibrate up and down at right angles to the direction of wave propagation.<\/strong><\/li>\n<\/ul>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter is-resized\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/lotusarise.com\/wp-content\/uploads\/2023\/06\/P-waves-S-waves.jpeg\" alt=\"P waves and S waves\" class=\"wp-image-40410\" width=\"425\" height=\"656\" title=\"\"><\/figure>\n<\/div>\n\n<style>.wp-block-kadence-spacer.kt-block-spacer-_da2d72-19 .kt-block-spacer{height:40px;}.wp-block-kadence-spacer.kt-block-spacer-_da2d72-19 .kt-divider{border-top-width:2px;border-top-color:#eee;width:100%;border-top-style:solid;}<\/style>\n<div class=\"wp-block-kadence-spacer aligncenter kt-block-spacer-_da2d72-19\"><div class=\"kt-block-spacer kt-block-spacer-halign-center\"><hr class=\"kt-divider\"\/><\/div><\/div>\n","protected":false},"excerpt":{"rendered":"<p>Which of the statements given above is\/are correct?
