What does the variable 'K' refer to in the context of Wein's Displacement Law?

In the context of Wein's Displacement Law, the variable 'K' refers to the constant of proportionality. This law describes the relationship between the temperature of an ideal black body and the wavelength at which it emits the maximum radiation. Specifically, Wein's Displacement Law states that the wavelength (λ_max) at which radiation is maximized is inversely proportional to the absolute temperature (T) of the black body. The equation is given by λ_max = K/T, where 'K' is a constant that allows for the proper scaling of the relationship.

Understanding 'K' as the constant of proportionality is crucial because it provides the mathematical basis for predicting peak emission wavelengths at different temperatures. This relationship is important in fields such as astrophysics, thermodynamics, and material science, where the behavior of radiation in relation to temperature is fundamental.

The other options do not represent what 'K' means in this context. For instance, absorptivity, specific heat, and emissivity factor pertain to different concepts regarding material properties and energy interactions, but they do not relate directly to the framework established by Wein's Displacement Law. Thus, recognizing 'K' as the constant of proportionality situates it correctly within the law's formulation and application
