Blackbody Radiation

原声例句
Crash Course Physics 速成课物理

You can predict the intensity of the energy coming from a blackbody – or blackbody radiation – based on its temperature.

您可以根据其温度预测来自黑体或黑体辐射的能量。

Crash Course 综合篇

If you take Planck’s law into account when you try to predict the intensity of blackbody radiation, you end up with an equation that predicts the experimental results perfectly, including those weird peak intensities.

如果在尝试预测黑体辐射强度时考虑普朗克定律，您最终会得到一个可以完美预测实验结果的方程式， 包括那些奇怪的峰值强度。

黑体辐射 Black-body radiation

（重定向自Blackbody Radiation）
不同温度的黑体辐射频谱。随着温度下降，频谱峰值波长增加
地球温度的黑体辐射

黑体辐射指处于热力学平衡态的黑体发出的电磁辐射。黑体辐射的电磁波谱只取决于黑体的温度。

或许我们换一个角度来说： 所谓黑体辐射其实就是光和物质达到平衡所表现出的现象。 物质达到平衡，所以可以用一个温度来描述物质的状态，而光和物质的交互作用很强，如此光和光之间也可以用一个温度来描述（光和光之间本身不会有交互作用，但光和物质的交互作用很强）。而描述这关系的便是普朗克分布（Planck distribution）。黑体辐射能量按波长的分布仅与温度有关。

黑体不仅仅能全部吸收外来的电磁辐射，且散射电磁辐射的能力比同温度下的任何其它物体强。

Black-body radiation 黑体辐射

（重定向自Blackbody Radiation）
As the temperature decreases, the peak of the black-body radiation curve moves to lower intensities and longer wavelengths. The black-body radiation graph is also compared with the classical model of Rayleigh and Jeans.
The color (chromaticity) of black-body radiation depends on the temperature of the black body; the locus of such colors, shown here in CIE 1931 x,y space, is known as the Planckian locus.
The temperature of a Pāhoehoe lava flow can be estimated by observing its color. The result agrees well with measured temperatures of lava flows at about 1,000 to 1,200 °C (1,830 to 2,190 °F).
9-year WMAP image (2012) of the cosmic microwave background radiation across the universe.[27][28]

Black-body radiation is the type of electromagnetic radiation within or surrounding a body in thermodynamic equilibrium with its environment, or emitted by a black body (an opaque and non-reflective body) held at constant, uniform temperature. The radiation has a specific spectrum and intensity that depends only on the temperature of the body.
