The effective temperature of the Sun (5778 kelvins) is the temperature a black body of the same size must have to yield the same total emissive power.. The effective temperature of a star is the temperature of a black body with the same luminosity per surface area (F Bol) as the star and is defined according to the Stefan–Boltzmann law F Bol = σT eff 4.
The temperature of stars other than the Sun can be approximated using a similar means by treating the emitted energy as a black body radiation. [27] So: = where L is the luminosity, σ is the Stefan–Boltzmann constant, R is the stellar radius and T is the effective temperature.
These particles form a part of the black body spectrum, in addition to the electromagnetic radiation. [52] A black body at room temperature (23 °C (296 K; 73 °F)) radiates mostly in the infrared spectrum, which cannot be perceived by the human eye, [53] but can be sensed by some reptiles. As the object increases in temperature to about 500 ...
However, in 2014, Southwest discontinued all service to the airport. [30] On July 15, 2017, Key West International Airport was awarded a grant of $6.5 million by the FAA to assist in a $10 million runway project. The project added 227 feet (69 m) to the runway for takeoffs and landings as well as added 10-foot (3.0 m)-wide shoulders paved on ...

A black body or blackbody is an idealized physical body that absorbs all incident electromagnetic radiation, regardless of frequency or angle of incidence. The radiation emitted by a black body in thermal equilibrium with its environment is called black-body radiation. The name "black body" is given because it absorbs all colors of light.
Sports Illustrated is about to break down some serious stereotypes. The magazine's 2016 Swimsuit Edition will feature some fresh faces and some new body types, proving that the mag is about more ...
The table on the right shows how the radiation of a black body at this temperature is partitioned, and also how sunlight is partitioned for comparison. Also for comparison a planet modeled as a black body is shown, radiating at a nominal 288 K (15 °C) as a representative value of the Earth's highly variable temperature.
