ألوان النار

06 أبريل 2013

ينطلق الضوء من النار في صورة لهـب Flame واللـهب له لون ممـيز يعتمد على مادة الاحتراق بدرجة رئيسـية ويعتمد أيضا على درجة الحـرارة. الالوان المـختلفة والصـادرة من اللهب هـي بسبب تغير درجة الحـرارة في شعلـة اللهب نفـسها. فالجزء الاسخن في اللـهب يكون في اسـفله والجزء الاكثر برودة في اعلىـ منطقة في اللهب.

ولهذا يبدو لون اللهب في الاسفل ازرق بينما أعلى اللهب يكون اللون قريـبا من اللون البرتقالي أو الأصـفر وهناك كذلك ألوان تظهر غير ذلك مثل الأحمر والأسود وبعض الأحيان وحسب المادة يكون هناك لون أرجواني أو أخضر.
