Question:

The human body has a surface area of approximately \(1.8 \mathrm{~m}^{2}\), a surface temperature of approximately \(30^{\circ} \mathrm{C}\), and a typical emissivity at infrared wavelengths of \(e=0.97\). If we make the approximation that all photons are emitted at the wavelength of peak intensity, how many photons per second does the body emit?
