    The PhET Interactive Simulations project at the University of Colorado Boulder creates free interactive math and science simulations. PhET sims are based on extensive education research and engage students through an intuitive, game-like environment where students learn through exploration and discovery. Oct 11, 2019 · A vibrating object in a medium, such as air, produces sound waves through the shifting of layers of air particles. This is similar to the longitudinal waves produced when a slinky spring is vibrated parallel to its length. A common vibrating source of sound is the tuning fork. A tuning fork is an instrument with two hard steel prongs.

  • Sound Waves in Air. A single-frequency sound wave traveling through air will cause a sinusoidal pressure variation in the air. The air motion which accompanies the passage of the sound wave will be back and forth in the direction of the propagation of the sound, a characteristic of longitudinal waves.

    A sound wave's frequency is a number that tells you how many waves pass by each second. Frequency is measured in Hertz (Hz). Frequency is measured in Hertz (Hz). So for example, 60 Hz, the ... 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).

  • The standing waves in a wind instrument are a little different from a vibrating string. The wave on a string is a transverse wave, moving the string back and forth, rather than moving up and down along the string. But the wave inside a tube, since it is a sound wave already, is a longitudinal wave; the waves do not go from side to side in the ...

In physics, sound is a vibration that propagates as an acoustic wave, through a transmission medium such as a gas, liquid or solid. In human physiology and psychology, sound is the reception of such waves and their perception by the brain.Use the Sound sim from PhET for questions 7 – 11. Play around and get familiar first. Select Audio Enabled to hear the sound. 7. Which type of wave is being shown by this sim - longitudinal or transverse? 8. When you change the frequency, how does the sound change? 9. How does the visual model change (include a diagram)? 10.
