Question

A lot of blackbody irradiation emanates from the surface of the earth. Recall that light energy (and energy from any region of the electromagnetic spectrum) is quantized. The energy of a photon can be calculated as follows:

E = hν = hcλ

where h is the Planck constant (6.626×10−34 J⋅s), and c represents the speed of light (2.998×108 m/s).

Calculate the energy (in joules) of each photon that is emitted from a patch of ground that is at 32 ∘C. Use the λmax of that temperature as your wavelength. Note that you can manually enter temperature values in the simulation in the white box.
