Like dominos, a wave motion is set off when an element sets the nearest particle of air into motion. This motion spreads to adjacent air particles further away from the source. Depending on the medium, sound propagates at different speeds. In air, sound propagates at a speed of approximately 340m/s. In liquids and solids, the propagation velocity is greater - 1500 m/s in water and 5000 m/s in steel.</p> </div> </div> <div class="vc_btn3-container vc_btn3-inline" > <a style="background-color:#24559a; color:#ffffff;" class="vc_general vc_btn3 vc_btn3-size-md vc_btn3-shape-rounded vc_btn3-style-custom vc_btn3-icon-right" href="/technology/" title="">MORE <i class="vc_btn3-icon fa fa-angle-right"></i></a></div> </div></div></div><div class="wpb_column vc_column_container vc_col-sm-6"><div class="vc_column-inner "><div class="wpb_wrapper"></div></div></div></div></div></div></div></div><div class="vc_row-full-width"></div> <div id="about" data-vc-full-width="true" data-vc-full-width-init="false" class="vc_row wpb_row vc_row-fluid color-changed vc_custom_1531928433073 vc_row-has-fill vc_row-o-equal-height vc_row-flex" style="color:#ffffff" > <div class="wpb_animate_when_almost_visible wpb_bounceInLeft bounceInLeft wpb_column vc_column_container vc_col-sm-6 vc_col-has-fill"><div class="vc_column-inner vc_custom_1532187420045"><div class="wpb_wrapper"> <div class=" text-left"><div class="m-b-40 custom-heading" ><h3 style="font-weight:500; font-size: 30px; color: #ffffff !important; ">About JL World</h3><span class="custom-heading-delim" style="border-top-color:#ffffff; width:30px;"></span></div></div> <div class="wpb_text_column wpb_content_element about_txt_white" > <div class="wpb_wrapper"> <p>JL World is a unique company with worldwide customers, a strong balance sheet and exciting growth potential.<br /> JL World's design and manufacturing activities are keenly targeted towards providing all our customers with competitive pricing, dependable reliability and winning performance across our core product families.
