Sound waves propagate through medium by vibrating particles. Watch how waves move from source to surroundings.
The origin point where vibrations begin and energy transfers to adjacent particles.
Particles oscillate parallel to wave direction in compressions and rarefactions.
Compression: Particles are close together
Rarefaction: Particles are spread apart
Wavelength: Distance between compressions
Frequency: Waves per second (Hz)
• Requires medium to propagate
• Speed in air: ~343 m/s
• Speed in water: ~1482 m/s
• Cannot travel in vacuum
• Adjust sliders to change wave properties
• Switch between wave types
• Use Start/Pause/Reset for animation control
