Webtrophysics. Specifically, I will discuss the history of Wien’s Displacement Law, including how it was developed and original uses. I will then derive Wien’s Displacement Law from Planck’s Law. I will show how Wien’s Displacement Law can be used to derive the temperature of stars from stellar spectra observations. WebWien’s Displacement Law Differentiating Planck’s function and setting the derivative equal to zero yields the wavelength of peak emission for a blackbody at temperature T λm ≈ 2900 T where λm is expressed in microns and T in degrees kelvin. This equation is known as Wien’s Displacement Law. 4
WebThe formula for Wien's displacement law is: λ m a x = b T Here, b is the Wien's constant, and T is the absolute temperature. Also, λ m a x is the peak wavelength that gives the maximum radiation a blackbody emits. The value of Wien's constant is b = 2. 9 × 10 - 3 mK. Example of Wien's displacement law
