- Slide: 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.
- Slide: 2
- Wavelength
- Wavelength is the length of one wave, measured in meters (m).
- Slide: 3
- Amplitude
- Amplitude is the height of a wave, measured in meters (m). The higher the amplitude, the higher the intensity of the wave.
- Slide: 4
- Ionizing
-
-
- A wave that can remove electrons from an atom, thus making them an ion, is said to be ionizing.
- Slide: 5
- Frequency
-
-
- Heinrich Rudolf Hertz
- Frequency is the number of waves to pass a point every second, measured in Hertz (Hz).
