Storyboard-Text

  • Gleiten: 1
  • Wave Speed
  • How fast a wave travels is called wave speed, measured in meters per second (m/s). All EM waves travel at the speed of light in a vacuum.
  • Gleiten: 2
  • Wavelength
  • Wavelength is the length of one wave, measured in meters (m).
  • Gleiten: 3
  • Amplitude
  • Amplitude is the height of a wave, measured in meters (m). The higher the amplitude, the higher the intensity of the wave.
  • Gleiten: 4
  • Ionizing
  • 
  • 
  • A wave that can remove electrons from an atom, thus making them an ion, is said to be ionizing.
  • Gleiten: 5
  • Frequency
  • 
  • 
  • Heinrich Rudolf Hertz
  • Frequency is the number of waves to pass a point every second, measured in Hertz (Hz).
