Your body, at a temperature of about 37° C (98.6°F), emits radiation in the infrared region of the spectrum.
a.) What is the peak wavelength of their radiation?
b.)
I know to use Wien’s law for part a), which is b/T with b= 2.9 x 10³ m. K and T your absolute temperature.
(Centigrade +273) = 37 C + 273 = 310
(2.9 x 10³) / 310 = 9.35 micron
