2019年9月12日 · Find out more about studying sound under water and read about what is needed for sound to be heard, and how sound travels through water to understand some of the key science concepts. Investigating waves and energy uses slinkies to explore longitudinal and transverse waves.

2023年11月8日 · Sound waves are fundamentally pressure waves, traveling through the compression and rarefaction of particles within a medium. Sound waves consist of areas where particles are bunched together, followed by areas where they're spread apart.

2023年9月12日 · In this post, we’ve taken a comprehensive look at sound waves, starting with the basics of what type of wave sound is—a longitudinal wave. We discussed its key aspects like frequency, amplitude, and speed in various media, breaking down how these properties shape our auditory experiences.

For a pure sound of only one frequency, like a tuning fork or whistling, the wave looks smooth and regular (as in the picture below). These are called sine waves. High notes have a high frequency and the waves are very close together. Low notes have a …

2014年11月24日 · Not the digital depiction of a sound wave - we mean the normally invisible, actual sound waves that leave a person's hands and travel outwards at over 1,200 km/h (761 miles per hour) when they clap. NPR's Skunkbear gives us a front-seat view.

Sound waves are produced by a vibrating object. Everything that makes a sound must have a part that vibrates. A sound wave is a longitudinal wave. When an object vibrates it produces a...

2023年2月8日 · Each sound wave has different parts, and understanding them will help you understand how the characteristics of sound are measured. Wave Crest – Just like on a wave in the ocean, the wave crest is the very top of the wave. Wave Trough – On the opposite side, we find the trough. This is the very bottom of the wave.
