      Vibrating matter

      • All sound waves begin with vibrating matter. The vibrations generate longitudinal waves that travel through matter in all directions.

    Sound waves travel through air at a rate of 343 m/s (768 mph) at 68 degrees F. The speed of sound changes slightly at different temperatures, and dramatically in different materials (for example, in steel alloy, it travels 6000 m/s and in fresh water at 25 degrees F, it travels at 1497 m/s).

    A sound wave is a mechanical wave that propagates along or through a medium by particle-to-particle interaction. As a mechanical wave, sound requires a medium in order to move from its source to a distant location. Sound cannot travel through a region of space that is void of matter (i.e., a vacuum).

    Jan 11, 2021 · All sound waves begin with vibrating matter. The vibrations generate longitudinal waves that travel through matter in all directions. Most sounds we hear travel through air, but sounds can also travel through liquids and solids.

    Longitudinal sound waves are used in ultrasound to do prenatal screening. Also, you can clean teeth using ultrasound, knock out small cancers, and obliterate kidney stones, all using ultrasound, which is sounds at a frequency in excess of 20,000 Hz.

  9. physics.info › soundThe Nature of Sound – The Physics Hypertextbook

    Sound is a longitudinal, mechanical wave. Sound can travel through any medium, but it cannot travel through a vacuum. There is no sound in outer space. Sound is a variation in pressure. A region of increased pressure on a sound wave is called a compression (or condensation).
