单词 Rayleigh Jeans law
释义

Rayleigh Jeans law

原声例句
Crash Course 综合篇

Once the frequency of light got into the ultraviolet range or higher, the Rayleigh-Jeans law didn’t fit the results of experiments at all.

一旦光的频率进入紫外线范围或更高,Rayleigh-Jeans 定律就完全不符合实验结果了。

Crash Course Physics 速成课物理

Once the frequency of light got into the ultraviolet range or higher, the Rayleigh-Jeans law didn't fit the results of experiments at all.

一旦光的频率达到一定程度的紫外线辐射或更高,瑞利-吉斯定律永远不会对应于实际结果。

Crash Course 综合篇

Even worse, if you summed up the contributions of higher and higher frequencies to calculate the total power emitted by a blackbody, the Rayleigh-Jeans law predicted that you’d find infinite power.

更糟糕的是,如果你将越来越高的频率的贡献相加来计算黑体发出的总功率,瑞利-金斯定律预测你会发现无穷大的功率。

Crash Course 综合篇

The equation they came up with, known as the Rayleigh-Jeans law, predicted that the higher the frequency of the radiation – and therefore, the shorter the wavelength – the higher the intensity.

他们提出的方程式被称为瑞利-金斯定律,预测辐射频率越高——因此波长越短——强度就越高。

瑞利-金斯定律 Rayleigh–Jeans law

(重定向自Rayleigh Jeans law)
瑞利-金斯定律、维恩定律 (-Wien's Law-)、普朗克定律,这三种定律的理论结果的比较。黑体温度是8 mK 。
Vergleich des Rayleigh-Jeans-Gesetzes (blau) mit dem wienschen (rot) und dem planckschen Strahlungsgesetz (schwarz), für einen Schwarzen Körper der Temperatur 1000 K.

瑞利-金斯定律是用于计算黑体辐射强度的一个定律。设w(\nu,T) 为辐射的能量密度,k是玻尔兹曼常数,c为真空中的光速,T是热力学温度,则


w(\nu,T)dv=\frac{8 \pi \nu^2}{c^3} kTdv

瑞利-金斯定律在波长较长时与实验相符。但是,在波长较短时,w趋向于无穷大,这于实验数据相违背。

Rayleigh–Jeans law 瑞利-金斯定律

(重定向自Rayleigh Jeans law)
Comparison of Rayleigh–Jeans law with Wien approximation and Planck's law, for a body of 8 mK temperature.
Vergleich des Rayleigh-Jeans-Gesetzes (blau) mit dem wienschen (rot) und dem planckschen Strahlungsgesetz (schwarz), für einen Schwarzen Körper der Temperatur 1000 K.

In physics, the Rayleigh–Jeans law attempts to describe the spectral radiance of electromagnetic radiation at all wavelengths from a black body at a given temperature through classical arguments. For wavelength λ, it is:

where c is the speed of light, kB is the Boltzmann constant and T is the temperature in kelvins. For frequency ν, the expression is instead
