Alpine Glow,Pala Group,Dolomites,Italy. At sunset,when the sun has just vanished below the horizon,high mountain tops that are still be illuminated by the sun become yellow,pink,reddish and finally purple (After Glow). This often spectacular change in color results from the selective scattering of sunlight by minute particles of dust and vapor in the earth`s atmosphere. Short-wave blue light is much more impaired by scattering than long-wave red light | |
