Sound, Hearing, and Music
Sound begins with a vibration and needs matter through which to travel. Your ear then turns a changing pressure pattern into nerve signals that the brain interprets. This lesson supports Chapter 15 of High School Physics. Sound is a mechanical pressure wave Sound cannot travel through a vacuum. In air, it moves as longitudinal compressions […]
Wave Motion
A wave carries energy and a pattern through space or a medium. The material in the medium may oscillate around equilibrium without traveling along with the wave. This lesson supports Chapter 14 of High School Physics. Amplitude, wavelength, and frequency measure different features Amplitude is the maximum displacement from equilibrium. Wavelength \(\lambda\) is the distance […]
