The Stefan-Boltzmann Law is a fundamental principle in physics that describes the total energy radiated per unit surface area from a blackbody (an idealized object that absorbs all incident radiation) as a function of its temperature.
The formula for the Stefan-Boltzmann Law is:
- E is the total energy radiated per unit surface area (in watts per square meter, W/m²).
- σ (sigma) is the Stefan-Boltzmann constant, approximately equal to 5.67 x 10^-8 W/(m²·K⁴).
- A is the surface area of the object emitting radiation (in square meters, m²).
- T is the absolute temperature of the object in kelvin (K).
