Waves. Sound is transmitted through gases, plasma, and liquids as longitudinal waves, also called compression waves. It requires a medium to propagate. Through solids, however, it can be transmitted as both longitudinal waves and transverse waves.
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.
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).
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
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.
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.
We can show sound waves by graphing either how particles move (displacement) or how squished together they are (density). But since density and pressure are related, a pressure vs time graph has the same form as a density vs time graph.
