SUMMARY
The total power emitted by the sun across all wavelengths can be calculated using the classical Rayleigh-Jeans expression for spectral radiance, represented by the equation ρt(v)dv = 8πv²kT/c³ dv. To find the total power, one must integrate this equation over all frequencies. This integration will yield the total power radiated by the sun, despite the Rayleigh-Jeans law being an approximation that fails at high frequencies.
