(a) assuming the human body (skin temperature 34◦ c) to behave like an ideal thermal radiator, find the wavelength where the intensity from the body is a maximum. in what region of the electromagnetic spectrum is radiation with this wavelength?
(b) making whatever (reasonable) assumptions you may need, estimate the power radiated by a typical person isolated from the surroundings.
(c) estimate the radiation power absorbed by a person in a room in which the temperature is 20◦ c.
