Dispersión de Partículas Atmosféricas Rayleigh (blue) • particle size < wavelength • affects shorter wavelengths more Mie (red) • particle size ≈ wavelength • affects longer wavelengths more Nonselective (white) • particle size much larger than wavelength • all wavelengths affected equally

Radiación Electromagnética Wavelength – the length of one full wave cycle, measured from the peak of one crest to the peak of the next. Frequency – the number of wave cycles passing a point in a given period of time.
Wavelength and frequency are inversely related.
