紫外灾变

紫外灾变,同样也被称为瑞利-金斯灾变,指的是19世纪末/20世纪初,科学家面对黑体辐射问题,透过以古典物理学为背景之瑞利-金斯定律,来计算黑体辐射强度与能量间之关系,却发现以古典物理学理论所计算之黑体辐射强度会随辐射频率上升,而趋向于放出无穷大之能量,其结果与实验数据无法吻合的历史事件。

紫外灾变这名词在1911第一次被保罗·埃伦费斯特给使用,但其概念是源自于1900年所推导的瑞利-金斯定律。

Ultraviolet catastrophe 紫外灾变

The ultraviolet catastrophe is the error at short wavelengths in the Rayleigh–Jeans law (depicted as
Energía radiada como función de la longitud de onda para varios cuerpos a diferentes temperaturas.
Vergleich des Rayleigh-Jeans-Gesetzes (blau) mit dem wienschen (rot) und dem planckschen Strahlungsgesetz (schwarz), für einen Schwarzen Körper der Temperatur 1000 K.

The ultraviolet catastrophe, also called the Rayleigh–Jeans catastrophe, was the prediction of late 19th century/early 20th century classical physics that an ideal black body at thermal equilibrium will emit radiation in all frequency ranges, emitting more energy as the frequency increases. When calculating the total amount of radiated energy, (ie, the sum of emissions in all frequency ranges), shows that it is infinite, contradicting the principles of conservation of energy.
