TWO IMPORTANT LAWS

Here I explain two important laws that I have studied. The wien's law and the boltzmann's law.

WIEN'S LAW

Wien's law is a law of physics. Specifies that there is an inverse relationship between the wavelength at which the emission peak of a black body occurs and its temperature. That means that hotter objects emit most of their radiation at shorter wavelengths; hence they will appear to be bluer. Colder objects emit most of their radiation at longer wavelengths; hence they will appear to be redder. As we can see in the next formula:

T=(2.9*10^(-3) k*m)/λmax

BOLTZMANN'S LAW

Stefan-Boltzmann law, statement that the total radiant heat power emitted from a surface is proportional to the fourth power of its absolute temperature. Specifically, the Stefan-Boltzmann law states that the total energy radiated per unit surface area of a black body across all wavelengths per unit time, is directly proportional to the fourth power of the black body's thermodynamic temperature.

The fornula is:

W (Radiated energy) = ε σ(Stefan's constant) T**4
