Students have asked these similar questions
Human body temperature is about 310 K (3.10 ✕ 102 K). At what wavelength (in nm) do humans radiate the most energy?
In which part of the electromagnetic spectrum (gamma-ray, X-ray, UV, visible light, IR, microwave, or radio) do we emit?
Suppose YOUR body temperature averages 98.6 F.
1. How much radiant energy in Wm^-2 is emitted from YOUR body?
2. What is the total radiant energy in W that is emitted from YOUR body?
3. At what wavelength does YOUR body emit the largest amount of radiant energy?
