Blackbody radiation experiment
WebIn Figure 8.1, the solar distribution is compared to a representative distribution, called a blackbody spectrum, that corresponds to a temperature of 5250 °C. The blackbody … WebThe concept of the blackbody is an idealization, as perfect blackbodies do not exist in nature. Experimentally, blackbody radiation may be measured as the steady state equilibrium radiation from a cavity in a rigid body. A good approximation of black body absorption is a small hole leading to the inside of a hollow object.
