Stevenson's Law is a principle in the field of physics that states the relationship between the temperature of an object and the energy it emits as radiation. Specifically, it asserts that the amount of energy radiated by a body is proportional to the fourth power of its absolute temperature. This means that even small increases in temperature can lead to significant increases in emitted energy. The law is often applied in various scientific fields, including astronomy and thermodynamics. It helps explain phenomena such as why hotter stars emit more light and energy compared to cooler ones, and it is fundamental in understanding heat transfer and energy conservation in different systems.
