Slide 11 - Tekstslide

The properties of a wave
Frequency
  •  The amount of waves per second — Unit: Hertz (Hz) — influences the tone of a sound

Amplitude
  •  The distance from the center of the wave to the top or the bottom in meters (m) — influences the loudness of a sound

Wavelength
  •  The length of one wave in meters (m)

Wave speed
  •  The speed of the wave in meters per second (m/s)
