Plank Radiation Spectrum Liquids Wavelength VS Temp

In summary, the conversation discusses the concept of Plank Radiation Spectrums for liquids and their behavior at different temperatures. The individual is curious about the specific wavelengths of light emitted by liquids at various temperatures, and provides examples such as the molten lava at the center of the Earth and a molten lake of steel. The conversation also mentions the possibility of liquids emitting light when heated and references the temperature of the Earth's core. However, the data on this topic is not readily available and may require the knowledge of exotic matter specialists.

Hello,

Are there any Plank Radiation Spectrums for liquids? What I really want to know is, for a given liquid, what wavelength of light is emitted for a given temperature. For example, if I journey to the center of the Earth, the molten lava is about a thousand degrees, hot enough to emit red light --> thus, it seems I would not be in a dark abyss if I travel to the center of the Earth but a glowing, red-yellow abyss all around me. Or if I fell into a molten lake of steel, this too would not be dark, but bright yellow (as seen from web page images). I could not find this kind of data on any liquid and guessed this concept would be where exotic matter specialists would be most likely to know.

About 6000 K in the core, as warm as the surface of sun.
Liquids won't be perfect black bodies, but they can be quite close. Yes, the emit light if you heat them. Steel is a nice example.
 

FAQ: Plank Radiation Spectrum Liquids Wavelength VS Temp

What is the Plank Radiation Spectrum of Liquids?

The Plank Radiation Spectrum of Liquids is a curve that shows the distribution of electromagnetic radiation emitted by a liquid at different wavelengths and temperatures. It is based on the work of physicist Max Planck and is used to understand the behavior of liquids at the atomic level.

How does the wavelength of light emitted by a liquid change with temperature?

As the temperature of a liquid increases, the wavelength of light it emits decreases. This is because the molecules in the liquid vibrate more intensely at higher temperatures, causing them to emit shorter wavelengths of light.

What is the relationship between temperature and the peak wavelength of light emission in liquids?

The peak wavelength of light emission in liquids is inversely proportional to temperature. This means that as the temperature increases, the peak wavelength decreases, and vice versa.

How does the Plank Radiation Spectrum of Liquids differ from that of solids or gases?

The Plank Radiation Spectrum of Liquids is unique because liquids have a wider range of wavelengths emitted compared to solids or gases. This is due to the fact that liquids have more degrees of freedom for molecular movement, leading to a broader distribution of wavelengths.

What applications does the Plank Radiation Spectrum of Liquids have in science and technology?

The Plank Radiation Spectrum of Liquids is used in various fields of science and technology, such as spectroscopy, thermometry, and astronomy. It is also essential in understanding the behavior of liquids in different environments, such as in space or in industrial processes.
