Previously, we looked at transverse waves. In contrast, some waves (such as sound waves in air) are longitudinal. In a longitudinal wave the particles vibrate parallel to the direction the wave is travelling in (not at 90 degrees as for waves on a string). What is being carried by the wave comes down […]
Introduction Waves are everywhere! In the air, in water, even in solid objects, visible and invisible, waves carry information – sometimes useful (like speech or TV data) and sometimes purely incidental (waves in the sea, or noise in the street). Visible waves are probably the easiest to think about, and […]
Welcome, this is a learning resource for wave and sound physics, mostly for the A-level curriculum. This site uses high speed video and animations to help explain waves and acoustics. It also includes links to career case studies, showing how acoustical and audio engineers use this knowledge in their jobs. Introduction […]
