Jul 23, 2023 · Water waves shake energy over the surface of the sea, while sound waves thump energy through the body of the air. Sound waves are compression waves. They're also called longitudinal waves because the air vibrates along the same direction as the wave travels.
Sound waves and units of measurement. Sound waves are longitudinal waves that travel through a medium like air or water. When we think about sound, we often think about how loud it is (amplitude, or intensity) and its pitch (frequency).
Nov 8, 2023 · Physical Science. Acoustics. Understanding Sound Waves and How They Work. Updated: Nov 8, 2023. Sound. When a drum is struck, the drumhead vibrates and the vibrations are transmitted through the air in the form of sound waves. When they strike the ear, these waves produce the sensation of sound.
The period of a sound wave is the time it takes for an air molecule to oscillate back and forth one time. The wavelength of a sound wave is the distance between two compressed regions of air. People get these mixed up because there's an alternate way to create a graph of this sound wave.
Explain the difference between sound and hearing; Describe sound as a wave; List the equations used to model sound waves; Describe compression and rarefactions as they relate to sound
About. Transcript. Sound is vibrating air. But how does the air start vibrating? Explore the intriguing science of sound waves and how they travel. Learn how speakers use oscillation to create sound, and discover why sound waves can transport energy without moving the medium itself.
