WebThe spectral irradiance from a blackbody is given by Planck's 1 radiation law, shown in the following equation: F λ = 2 π h c 2 λ 5 e x p h c k λ T - 1. where: λ is the wavelength of light; T is the temperature of the blackbody (K); F is the spectral irradiance in Wm -2 µm -1; and. h,c and k are constants. Getting the correct result ... WebQuantitatively, Wien’s law reads. λ max T = 2.898 × 10 −3 m · K. 6.1. where λ max is the position of the maximum in the radiation curve. In other words, λ max is the wavelength at which a blackbody radiates most strongly at a given temperature T. Note that in Equation 6.1, the temperature is in kelvins.

If you didn't get the black body radiation curve, could you sketch the shape of the graph? One possibility is that the absolute values of x in such a curve are relatively small, and your graphical calculator might not be able to handle that. Additionally, your graphical calculator may be truncating the top half of the curve.
