Wien's law is stated as \( \lambda_m T = C \),
where
\( C = 2898\ \mu\text{mK} \)
and \( \lambda_m \)
is the wavelength at which the emissive power of a black body is maximum for a given temperature T.
The spectral hemispherical emissivity curve shows a maximum at \( \lambda_m \approx 6000\ \text{\AA} \).
The temperature at which the total hemispherical emissivity is highest is ________________ K (nearest integer).
