Sound Wave Experiments • In this video, we are going to look at the factors that influence the speed of sound and how to measure it. • We will look at sound waves in more detail in another video: Sound Waves • Sound travels at about 340m/s in air. At sea level. At 20 degrees celsius. • What does this tell us? • That temperature and air pressure affect the speed sound can travel through air. And this speed changes again for different mediums. • How is this possible? It’s all to do with particles. Let’s look at some evidence. • So sound travels at about 340 m/s in air. • In water, it travels at 1500 m/s, While in some solids sound can travel at up to 5000 m/s. • That’s incredibly fast compared to air!! • These differences are due to how particles are arranged in solids, liquids, and gases. • CREDITS • Animation Design: Reshenda Wakefield • Narration: Dale Bennett • Script: Bethan Parry • VISIT US • Website: www.fuseschool.org • Twitter: / fuseschool • Instagram: https://www.instagram.com/fuseschool/... • Facebook: / fuseschool • This Open Educational Resource is free of charge, under a Creative Commons License: Attribution-NonCommercial CC BY-NC.
