The correct answer is:
The amount of energy radiated by a blackbody per square meter of its surface per second.
Explanation: The Stephan-Boltzmann law is a fundamental principle in physics that relates the total power radiated by a blackbody to its temperature. It states that the power radiated by a blackbody is directly proportional to the fourth power of its temperature. Mathematically, this relationship can be expressed as:
P = σT^4
Where P is the power radiated, T is the temperature in Kelvin, and σ is the Stefan-Boltzmann constant.
By knowing the temperature of the blackbody, we can use the Stephan-Boltzmann law to compute the amount of energy radiated by the blackbody per square meter of its surface per second. This calculation is useful in various fields such as astrophysics and engineering, where understanding the radiation emitted by objects is important for designing and analyzing systems.
