Why is glacier ice blue?<\/b><\/h2>\n

 <\/p>\n

Glacier ice appears blue to us for the same reason that the ocean appears to be blue. The wavelengths of the visible spectrum of light that are reds and greens (500-740 nm) are preferentially absorbed by water and ice while the shorter wavelengths of the visible spectrum (the blues and purples, 380-500 nm) are typically reflected and are visible to the human eye 1<\/sup>. The longer the light travels into the object, the more blue it will appear, which also why we do not perceive this effect when we put an ice cube in our soda.<\/p>\n

\u00bfPor qu\u00e9 el hielo glaciar es azul?<\/strong><\/h2>

\u00a0<\/p>

El hielo del glaciar nos parece azul por la misma raz\u00f3n que el oc\u00e9ano parece azul. Las longitudes de onda del espectro visible de la luz que son rojas y verdes (500-740 nm) son absorbidas preferentemente por el agua y el hielo, mientras que las longitudes de onda m\u00e1s cortas del espectro visible (azules y p\u00farpuras, 380-500 nm) se reflejan t\u00edpicamente y son visibles para el ojo humano 1<\/sup>. Cuanto m\u00e1s tiempo viaja la luz en el objeto, m\u00e1s azul aparecer\u00e1, lo que tambi\u00e9n explica por qu\u00e9 no percibimos este efecto cuando colocamos un cubo de hielo en nuestra bebida.<\/p>
