Kelvin, bilimde kullan\u0131lan mutlak bir s\u0131cakl\u0131k birimidir.<\/p>\n

Kelvin defi<\/a> cinsinden bir \u0131\u015f\u0131k kayna\u011f\u0131n\u0131n, bir monit\u00f6r\u00fcn veya bir g\u00f6r\u00fcnt\u00fcn\u00fcn renk s\u0131cakl\u0131\u011f\u0131<\/a>, tamamen siyah bir nesnenin bu beyazl\u0131kta parlamas\u0131 durumunda s\u0131cakl\u0131\u011f\u0131na kar\u015f\u0131l\u0131k gelir. \u0130\u015fte daha ayr\u0131nt\u0131l\u0131 bir a\u00e7\u0131klama:<\/p>\n

Siyah cisim radyat\u00f6r\u00fc ve Planck'\u0131n radyasyon yasas\u0131:<\/h3>\n

Siyah cisim, s\u0131cakl\u0131\u011f\u0131n\u0131n bir fonksiyonu olarak elektromanyetik radyasyon yayan varsay\u0131msal bir nesnedir. Max Planck, siyah bir cismin radyasyon \u00f6zelliklerini tan\u0131mlamak i\u00e7in Planck'\u0131n radyasyon yasas\u0131n\u0131 geli\u015ftirmi\u015ftir. Bu yasa, yay\u0131lan radyasyonun spektral da\u011f\u0131l\u0131m\u0131n\u0131n siyah cismin s\u0131cakl\u0131\u011f\u0131na ba\u011fl\u0131 oldu\u011funu belirtir. Daha y\u00fcksek s\u0131cakl\u0131klarda, siyah cisim daha k\u0131sa dalga boylar\u0131nda (daha y\u00fcksek frekanslarda) daha fazla enerji yayar ve \u0131\u015f\u0131\u011f\u0131n mavimsi renkte g\u00f6r\u00fcnmesine neden olur. Daha d\u00fc\u015f\u00fck s\u0131cakl\u0131klarda, daha uzun dalga boylar\u0131ndaki (daha d\u00fc\u015f\u00fck frekanslar) emisyon daha y\u00fcksektir ve \u0131\u015f\u0131\u011f\u0131n k\u0131rm\u0131z\u0131ms\u0131 g\u00f6r\u00fcnmesine neden olur.<\/p>\n

Ger\u00e7ek \u0131\u015f\u0131k kaynaklar\u0131na uygulama:<\/h3>\n

Pratikte ampuller, floresan lambalar, g\u00fcn \u0131\u015f\u0131\u011f\u0131 vb. gibi ger\u00e7ek \u0131\u015f\u0131k kaynaklar\u0131 m\u00fckemmel siyah yay\u0131c\u0131lar olarak kabul edilemez. Bununla birlikte, Planck'\u0131n radyasyon yasas\u0131n\u0131 kullanarak, bu kayna\u011f\u0131n ideal siyah radyasyonla sahip olaca\u011f\u0131 \u0131\u015f\u0131\u011f\u0131n renk tonunu tan\u0131mlayan bir s\u0131cakl\u0131k tan\u0131mlayabiliriz. Tan\u0131mlanan bu s\u0131cakl\u0131k Kelvin cinsinden \u00f6l\u00e7\u00fcl\u00fcr ve \"\u0131\u015f\u0131k s\u0131cakl\u0131\u011f\u0131\" olarak adland\u0131r\u0131l\u0131r.<\/p>\n
