Electromagnetic Waves
¥Two important aspects of waves are:
–What kind: Wavelength or distance between peaks.
–How much: Amplitude or distance between peaks and valleys.
Wavelength
Amplitude
Frequency
The picture of electromagnetic waves passing through the atmosphere is much like that of the waves on the surface of the water.  There are two important aspects about the waves:
1. What kind of wave is it?:  Wavelength or distance between the peaks of the waves.
2. How big is it?: Amplitude or distance between peaks and valley.  When more radiation is emitted, the amplitude increases.
