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. WebA unit area of a black body radiates a “flux” of energy given as: F = σT4, where σ = 5.67×10−5 erg s −1 cm 2 deg−4 is the Stefan-Boltzman constant. The flux of energy is measured in [erg s−1 cm−2], A star with a radius R and luminosity L has an “effective” temperature Teff defined with the relation: L = 4πR2σT4 eff. can my dog have piriteze https://themarketinghaus.com
