Sound Waves

Speed: 343 m/s (air), 1,482 m/s (water)

Audio frequencies, ultrasound, seismic waves

How to Use

  1. 1. Enter any two known values (frequency, wavelength, or speed)
  2. 2. Select appropriate units for your calculation
  3. 3. The third value is calculated automatically
  4. 4. Use preset mediums for common wave types
