Chapter 38, Problem 45P

To determine

To find:

a) the wavelength at which your spectral radiancy is maximum (assuming that your body is a black body radiator).

b) the power at which you emit thermal radiation in a wavelength range of $1.00 nm$ at the wavelength calculated in (a) from a surface area of $4.00 c{m}^2$.

c) the rate at which you emit photons from that surface area

Now, assume that the wavelength is $500 nm$(visible range)

d) Recalculate the power.

e) Recalculate the rate of photon emission.
