Quin invisible fenomen ha fet explotar els globus a dist\u00e0ncia?<\/strong><\/p>\n

Els globus exploten perqu\u00e8 la goma de qu\u00e8 estan fets s\u2019escalfa amb l\u2019energia que absorbeix de<\/p>\n

la llum. Quan s\u2019escalfa, s\u2019estira, i aix\u00f2 fa que la goma es trenqui i el globus exploti. Cada globus<\/p>\n

absorbeix l\u2019energia de la llum que no ha reflectit. Aix\u00ed doncs, el blanc la reflectir\u00e0 tota, el negre<\/p>\n

l\u2019absorbir\u00e0 tota i els de colors absorbiran tota la llum menys la del seu color.<\/p>\n

De quin color \u00e9s la llum del sol?<\/strong><\/p>\n

La llum del sol cont\u00e9 molts tipus de llum que percebem de diverses maneres. Cont\u00e9 rajos<\/p>\n

ultraviolats, tot l\u2019espectre de llum visible (tots els colors) i rajos infrarojos.<\/p>\n

Per qu\u00e8 veiem els globus de diversos colors si tots estan il\u00b7luminats per la mateixa llum, la del sol?<\/b><\/p>\n

La llum del sol il\u00b7lumina diferents objectes i, quan incideix a la seva superf\u00edcie, es reflecteix.<\/p>\n

Aquests rajos reflectits s\u00f3n els que arriben als nostres ulls i ens permeten veure els objectes sobre<\/p>\n

els quals s\u2019han reflectit.<\/p>\n

Per qu\u00e8 veiem uns objectes de color vermell i uns altres de color blau si tots estan il\u00b7luminats per la llum del mateix sol?<\/strong><\/p>\n

Els globus absorbeixen una quantitat de llum i reflecteixen la resta. Els veiem del color de la llum<\/p>\n

que reflecteixen, que \u00e9s la que arriba als nostres ulls. Com que la llum del sol inclou tots els colors<\/p>\n

de l\u2019espectre, podem veure\u2019ls de qualsevol color.<\/p>\n
