Question #232133

Calculate the maximum monochromatic emissive power at 288K?

Expert's answer

According to Wien's displacement law, we have

\lambda=\frac bT.

The maximum monochromatic emissive power is

E=\frac{2hc^2}{\lambda^5}·\frac{1}{e^{\frac{hc}{\lambda kT}}-1}.

Substitute the wavelength:

E=\frac{2hc^2T^5}{b^5}·\frac{1}{e^{\frac{hc}{b k }}-1}=8.12·10^6\text{ W/m}^2.
