How frequency affects the rate of heat transfer
Thermal energy refers to the energy transferred between objects due to a temperature difference. One aspect that influences the rate of heat transfer is the frequency of the thermal radiation emitted by an object.
The frequency of thermal radiation is directly related to the object’s temperature. According to the laws of thermodynamics, hotter objects emit thermal radiation with higher frequencies, which corresponds to shorter wavelengths. As the frequency increases, the rate of heat transfer between objects also increases. This is because the higher frequency radiation carries more energy per photon.
The Stefan-Boltzmann law quantitatively describes the relationship between the temperature of an object and the radiated thermal energy. It states that the total power radiated by an object is proportional to the fourth power of its temperature. Mathematically, it can be expressed as P ∝ T^4, where P represents the radiated power and T is the temperature in Kelvin. This means that as the temperature increases, the power radiated (and hence the rate of heat transfer) increases exponentially.
