   Jul 23, 2023 · Measuring waves. All sound waves are the same: they travel through a medium by making atoms or molecules shake back and forth. But all sound waves are different too. There are loud sounds and quiet sounds, high-pitched squeaks and low-pitched rumbles, and even two instruments playing exactly the same musical note will produce sound waves that are quite different.

   Dec 28, 2020 · Sound is a type of mechanical wave or an oscillation of matter. When a sound wave propagates through a medium, such as air, it does so by causing the air molecules to vibrate, which causes changes in air pressure. The speed of sound in air is around 343 m/s but can vary with temperature.

    Sep 21, 2019 · Sound waves travel through the air at a speed of about 1 235 km/h at sea level! What is Pitch and Frequency? Wavelength determines a sound’s frequency. Wavelength is the distance between waves. For sound waves, wavelength refers to one complete cycle of rarefaction. The shorter the wavelength, the higher the frequency of the sound.
