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. WebSep 12, 2024 · In a classical approach to the blackbody radiation problem, in which radiation is treated as waves (as you have studied in previous chapters), the modes of electromagnetic waves trapped in the cavity are in equilibrium and continually exchange their energies with the cavity walls.
