At what wavelength does your body radiate the most given that your temperature is approximately that of the Earth, which is 300 K? A) 10^-⁵ m B) 10^-³ m C) 10^-² m D) 10 m E) 1,000 m

Question

Quizplus · Accepted Answer

Wien's displacement law states that the wavelength of maximum emission is inversely proportional to the temperature of the object. The higher the temperature, the shorter the wavelength. The temperature of the human body is approximately 300 K, which is close to the temperature of the Earth. Therefore, the wavelength of maximum emission for the human body is approximately 10 μm, which is in the infrared region of the spectrum.
