Black body temperature of the sun
WebStep-by-step explanation. The radiation laws, also known as the laws of blackbody radiation, are a set of physical laws that describe the emission and absorption of electromagnetic radiation by matter. These laws form a basis for the study of the physics of radiation in many areas, including astronomy, astrophysics, geophysics, and climate science. WebApr 12, 2024 · Infrared signature of targets is one important approach for target detection and recognition. When measuring the infrared signature of a target in the atmosphere, it is necessary to take the atmospheric transmittance and atmospheric radiation between the measured target and the observer into account. In this study, a blackbody-based …

WebNov 15, 2011 · Ok thanks I see. So the fact that I see wavelengths that are brigther than a black body at 5777 K does imply that there are regions over the Sun's surface that are hotter than 5777 K. Thus the answer of Redbelly98 is right. But is there a way to mathematically deduce that a black body would radiate more than a gray body for any … WebMar 5, 2024 · The "blackbody spectrum" you showed first is just a representation of perceived colour vs temperature of the black body. Not an actual spectrum. This is all just a coincidence.... (for example, the sun's colour in the first image is between 5500 and 6000...actually close to our perception of white) – José Andrade.
With his law, Stefan also determined the temperature of the Sun's surface. He inferred from the data of Jacques-Louis Soret (1827–1890) that the energy flux density from the Sun is 29 times greater than the energy flux density of a certain warmed metal lamella (a thin plate). A round lamella was placed at such a distance from the measuring device that it would be seen at the same angular …
